Gently mix the minced kidney with RPMI 1640 and transfer into tubes.
Incubated the minced kidney in RPMI 1640 medium containing 0.5 mg/mL Liberase(Cat# 423610, Roche) and 100 U/mL DNase I (Cat# D8071, Solarbio) at 37°C for at least 45 min.
Add 0.1% bovine serum albumin to stop the enzymatic reaction.
After filtration and red blood cell lysis, Centrifuge the mixture for 10 min and remove the supernatant.
