5. Be careful not to submerge the entire vial Maximum cell viability is dependent on the rapid and complete thawing of frozen cells IMPIOO47A2 SCCAC 00001 Page 4 of 8 co cyagen Note Results will be less than optimal if the cells are thawed for more than 3 minutes 5 As soon as the cells are completely thawed disinfect the outside of the vial with 70 v v ethanol 6 Use a pipette to transfer the cells to the 15mL conical tube containing OriCell Astrocyte Growth Medium inside a biosafety cabinet Be careful not to introduce any bubbles during the transfer process 7 Rinse the vial with 1mL of medium to reduce the loss of cell and then transfer this 1mL of cell suspension to the conical tube 8 Gently mix the cell suspension by slowly pipetting up and down Be careful not to introduce any bubbles 9 Centrifuge the cell suspension at 250 x g for 5 minutes 10 Carefully aspirate off as much of the supernatant as possible and add 2 3mL of fresh OriCell Astrocyte Growth Medium pre warmed to 37 C 11 Gently re suspend the cells in OriCell 12 Seed the cells into a T25 flask and add a sufficient OriCell Astrocyte Growth Medium Gently rock the culture flask to evenly distribute the cells 13 Incubate the flask at 37 C in a 5 CO humidified incubator Astrocyte Growth Medium 14 The next day change the medium with fresh OriCell pre warmed to 37 C Astrocyte Growth Medium 15 Change the growth
