I.    General Instructions for Use for the Cryopreservation of Mammalian Cells

 

Notes:

•    For freezing human Induced Pluripotent and Embryonic Stem Cells (hPSC) see section II.

•    For freezing human Mesenchymal Stem Cells (hMSC) see section III.

•    Keep BeautiFreez D20 Cryopreservation Medium on ice at all times during use.

•    For freezing adherent cells, detach cells using a dissociation solution according to the manual instructions.

 

Freezing procedure

 

1.    To maintain aseptic work conditions, wipe the outer packaging with a cloth moistened in 70% Ethanol/70% Isopropanol before opening the BeautiFreez D20 Cryopreservation Medium.

2.    Centrifuge cells to obtain a cell pellet, 300-400xg for 4-5 minutes, then aseptically decant supernatant without affecting the cell pellet.

3.    Suspend the pellet in cold (2 - 8°C) BeautiFreez D20 Cryopreservation Medium, mix thoroughly, and transfer the suspension to a cryovial (e.g., 1.0 mL of suspension in a 1.5 mL cryovial).

Note: If freezing multiple cryovials, keep the cells on ice at all times. Gently mix the resuspended cell solution

frequently to ensure even distribution throughout the vials. Immediately transfer filled cryovials to ice before aliquotting the remaining cell solution.

4.    Freeze the cells gradually (1-2°C per minute) by using a controlled rate freezing system and store the vials in

liquid nitrogen (vapor phase). Alternatively, place the vials in appropriate freezing container (e.g. Mr. Frosty) and transfer to -80°C for overnight. The following day transfer cryovials into liquid nitrogen (vapor phase recommended).

Note: long-term storage at -80°C is not recommended.

5.    It is recommended to determine the efficiency of cryopreservation by thawing one vial after 24 hours of storage in liquid nitrogen and following the thawing procedure outlined below.

 

 

Thawing of cryopreserved cells:

 

1.    Briefly warm culture medium of choice in a 37°C water bath.

2.    Rapidly thaw the cryovial of cells in a 37°C water bath by gently shaking the vial and remove the vial when only a small frozen cell pellet remains. Do not vortex cells.

3.    Disinfect the vial by wiping it down with a cloth moistened with 70% Ethanol or Isopropanol.

4.    Suspend the cells in warmed growth culture medium at a ratio of at least 1:10 (cell suspension to culture medium).

5.    Centrifuge cells to obtain a cell pellet, 300-400 x g for

4-5 minutes, then aseptically decant supernatant without affecting the cell pellet and resuspend in growth medium as desired.

6.    Culture the cells according to the recommended seeding density.

 

Instructions for Use for the Cryopreservation

of Human Induced Pluripotent and Embryonic Stem Cells (hPSC)

 

Notes:

•    hPSC may be frozen as clumps or single cells with high viability and minimal differentiation post thaw.

•    The single cells can be thawed onto recombinant Laminin coated culture ware without the addition of ROCK inhibitors. In case of using other matrices (e.g. Matrigel™), Rock inhibitor is required.

•    Keep BeautiFreez D20 Cryopreservation Medium on ice at all times during use.

 

 

The procedure describes the cryopreservation of cells cultured in a 6-well plate.

 

1.     Using a vacuum aspirator and a sterile aspirator pipette, remove the hPSC culture medium from the culture vessel or well(s) to be harvested for cryopreservation.

2.     Rinse wells with Dulbecco’s PBS w/o Ca & Mg (Cat#

NA023-500ML), using approximately 2mL of DPBS per 10cm2 culture surface area, then aspirate out the DPBS.

3.     Determine the desired viable cell density and calculate the required volume of BeautiFreez D20

Cryopreservation Medium needed for a concentration of approximately 1×106 viable cells/mL.

4.     Add dissociation solution as desired. Cells may be detached using the enzyme and method that the culture has been routinely passaged with.

In case of using Collagenase, Dispase or EDTA, incubate at 37°C or at room temperature until the edges of the colonies begin to loosen from the plate.

Note: Incubation times may vary between cell lines, colony size and the detachment solution used. Begin checking the culture after 3 minutes.

5.     Cells cultured on Laminin may be detached using Recombinant Trypsin-EDTA Solution (Cat# 03-079-1) to yield a single cell suspension.

Note: Once the cells are detached from the surface, neutralize the enzyme by adding 2-4 volumes of pre-warmed complete medium to the volume of the trypsin solution used. Alternatively, 1X Soybean Trypsin Inhibitor (SBTI) solution (Cat. No. 03-048-1) diluted in DPBS can be used to neutralize the trypsin.

6.     Transfer the clumps or cell suspension to a centrifuge tube.

7.     Centrifuge at 200 x g for 5 minutes at room temperature then aseptically decant supernatant without affecting the cell pellet.

8.     Resuspend the cell pellet in the pre-determined volume of cold BeautiFreez D20 Cryopreservation Medium on ice (1mL for every 1×106 viable cells). In case of aggregates; do not break up cell masses any more than necessary, two or three gentle pipetting motions are usually sufficient.

9.     Dispense aliquots of this suspension into cryo vials (e.g., 1.0mL of suspension in a 1.5mL cryovial)

Note: If freezing multiple cryovials, keep the cells on ice at all times. Gently mix the resuspended cell solution

frequently to ensure even distribution throughout the vials. Immediately transfer filled cryovials to ice before aliquotting the remaining cell solution.

10.  Freeze the cells gradually (1-2°C per minute) by using a controlled rate freezing system and store the vials in

liquid nitrogen (vapor phase). Alternatively, place the vials in an appropriate freezing container (e.g. Mr. Frosty) and transfer to -80°C overnight.

11.  The following day, transfer vials to liquid nitrogen storage (vapor phase).

Note: Long term storage at -80°C is not recommended

 

Thawing of Cryopreserved hPSC

 

1.        Briefly warm BeatiStem® hPSC XF Medium, or other growth culture media of choice, in a 37°C water bath.

2.        Add 9ml of warmed BeatiStem® hPSC XF Medium, or other growth culture media, into a centrifuge tube.

3.        Rapidly thaw the cryovial of cells in a 37°C water bath by gently shaking the vial and remove the vial when only a small frozen cell pellet remains. Do not vortex cells.

4.        Disinfect the vial by wiping it down with a cloth moistened with 70% Ethanol or Isopropanol.

5.        In a sterile biological safety cabinet, transfer the contents of the cryovial drop by drop into the 9mL of culture medium in the previously prepared centrifuge tube. Gently rock to continually mix the cells as the new cell droplets are added to the tube.

6.        Centrifuge the cells at 200 x g for 5 minutes. Remove and discard supernatant.

7.        Gently resuspend the cell pellet in BeatiStem® hPSC XF Medium (Cat# 05-100-1) or other growth culture media, and plate as desired.

                8.          Refresh culture medium 48 hrs after plating.

 

I.           Instructions for Use for Cryopreservation of Human Mesenchymal Stem Cells (hMSC)

 

Note:

•    Keep BeautiFreez D20 Cryopreservation Medium on ice at all times during use

Freezing procedure of hMSC

1.        Using a vacuum aspirator and a sterile aspirator pipette, remove the hMSC culture medium from the culture vessel or well(s) to be harvested for cryopreservation.

2.        Rinse wells with Dulbecco’s PBS w/o Ca & Mg (Cat#

02-023-1), using approximately 2mL of DPBS per 10 cm culture surface area, then aspirate out the DPBS.

3.        Detach adherent hMSC using a sufficient volume of Recombinant Trypsin Solution (Cat. No. 03-078-1) to cover the entire cell culture surface and incubate the cells at room temperature or 37°C for 3 to 5 minutes.

Note: Recombinant Trypsin-EDTA Solution (Cat. No. 03-079-

1) can be used if the cells are over-confluent or are difficult to detach after a short incubation with Recombinant Trypsin Solution.

4.        Observe the cells under a microscope. If less than 90% of the cells are detached from the culture surface, continue incubating and observe again at 1-minute intervals to check for complete detachment.

Note: Incubation times will vary between cells and confluency levels. Begin checking the cultures after 3 minutes. Do not over-incubate the culture, as MSC can be sensitive to enzymatic stress. Tap the vessel periodically to expedite cell detachment and monitor the progress of the enzyme solution.

5.        Once the cells are detached from the surface, neutralize the action of the trypsin enzyme by adding a volume of pre-warmed complete medium that is 2 to 4 times the volume of the trypsin solution used.

Note: Alternatively, 1X Soybean Trypsin Inhibitor (SBTI) solution (Cat. No. 03-048-1) diluted in DPBS can be used to neutralize the trypsin.

6.        Collect the cell suspension and transfer to a centrifuge tube. If needed, rinse the culture vessel with additional media to collect any remaining cells, and transfer to the same tube.

7.        Centrifuge at 300x g for 5 minutes at room temperature, and then aseptically decant supernatant without affecting the cell pellet.

8.        Resuspend the pellet in the amount of complete media (approximately 3-5mL) required to perform a cell count to determine the total viable cell number (e.g, using Trypan Blue Exclusion Assay).

9.        Centrifuge the cell suspension at 300x g for 5 minutes at room temperature.

10.    Determine the required volume of BeautiFreez D20 Cryopreservation Medium needed for a concentration of approximately 1×106 viable cells/mL.

11.    Remove the supernatant from the centrifuge tube and quickly but gently resuspend the pellet in cold

BeautiFreez D20 Cryopreservation Medium according to the freezing volume determined in the previous step.

12.    Dispense aliquots of this suspension into cryovials (e.g., 1.0mL of suspension in a 1.5mL cryovial).

Note: If freezing multiple cryovials, keep the cells on ice at all times. Gently mix the resuspended cell solution frequently to ensure even distribution throughout the vials.

Immediately transfer filled cryovials to ice before aliquotting the remaining cell solution.

13.    Freeze the cells gradually (1-2°C per minute) by using a controlled rate freezing system and store the vials in liquid nitrogen (vapor phase). Alternatively, place the vials in appropriate freezing container (e.g. Mr. Frosty) and transfer to -80°C for overnight.

14.    The following day, transfer the cryovials into liquid nitrogen (vapor phase).

Note: long-term storage at -80°C is not recommended.

It is recommended to determine the efficiency of cryopreservation by thawing one vial after 24 hours of storage in liquid nitrogen and following the thawing procedure outlined below.

Thawing of Cryopreserved hMSCs

 

1.        Briefly warm 5-10mL of complete MSC BeatiStem® XF Medium (Cat. No. 05-200-1 and 05-201-1) or other growth culture medium, in a 50mL centrifuge tube.

2.        Rapidly thaw a cryovial of hMSC in a 37°C water bath, by gently shaking the vial and remove the vial when only a small frozen cell pellet remains. Do not vortex cells.

3.        Disinfect the vial by wiping it down with a cloth moistened with 70% Ethanol or Isopropanol.

4.         In a sterile biological safety cabinet, transfer the  contents of the cryovial drop by drop into culture medium in the previously prepared centrifuge tube. Gently rock to continually mix the cells as the new cell droplets are added to the tube, then resuspend the cells by carefully pipetting up and down.

5.         Centrifuge cells at 300x g for 4-5 minutes at room temperature.

Note: It is possible to skip the centrifugation step after thawing by simply transferring the thawed cells directly onto a culture vessel with medium at a ratio of at least 1:10 (for the dilution of the DMSO).

                 6.        Remove supernatant and resuspend cell pellet in  0.5-1 ml of complete  MSC  BeatiStem®  XF  Medium or other culture medium.

                 7.       Perform a viable cell count (e.g, using Trypan Blue Exclusion Assay).

                 8.       Add the desired volume of complete MSC BeatiStem® XF Medium or other culture medium.

                  9.       Culture cells as desired and incubate in a humidified CO2 incubator (37°C).

10.       Refresh culture medium 48 hrs. after plating
