Protocols#
Thawing cells from freezing cells
Thawing matrigel stock solution on ice (1.5 ml tube)
Add cold 10ml of DMEM/F12 into 15ml of falcon tube.
Important
Must use cold DMEM/F12
Add Matrigel solution into prepared 10ml of DMEM/F12 in 15 ml falcon tube
Coat 6 well late with Matrigel , and incubator for one hour at RT
6 well plate: 1 mL per well
Important
Do not put into incucator
Thawing the cells in freezing vial (from LN2 Tank) at 37C water bath
Add 4 ml of mTeSR plus new 15 ml falcon tube.
Add 1 ml of cell suspention from freezing vial into 15 ml of falcon tube.
Centrifuge 15ml of falcon tube at 1000 rpm for 3 min at RT.
Aspirate supernatant
Add 2 ml of fresh mTeSR plus into 15 ml of falcon tube containing cell pelet. Pipette and mix for several times.
Important
Do not mix more than 5 times, use 5 ml of pipette
Transfer cell suspension to 6 well plate
Place 6 well plate into incubator.
Medium change
Aspirate mTeSR plus from 6 well plate
Add 2 ml of mTeSR plus into 6 well plate
Subculture
Aspirate culture medium from 6 well plate
Add 1ml of ReLeSR™ into 6 well plate
Aspirate ReLeSR™ from 6 well plate
Incubate the plate for 3-5 min
Add flesh 1 ml of mTeSR plus, and then tapping the plate for 10-30 sec until you can see floating cells and to get 30-50 um of cell colony.
collect all soulstion into a 15mL falcon tube.
Add 7 ml of mTeSR plus into falcon tube.
2 ml of cell suspension into Matrigel coatd 6 well plate
Place 6 well plate on incubator.
