Protocol Neural Maintenance Medium Neural Induction Medium Supplements Notable Differences

Shi et al. 2012 N2/B27 medium.
N2 medium: Basal medium with 1% N-2 supplement, 1% 200mM L-alanyl-L-glutamine dipeptide in 0.85% NaCl solution, 1% pen/strep, 5ug/mL insulin, 1mM ;-glutamine, 100μM non-essential amino acids, 100μM 2-mercaptoethanol. B27 medium: DMEM/F12 supplemented with 2% B-27 supplement, 200mM L-glutamine, 1% pen/strep.
N2/B27 medium supplemented with 10μM SB431542 and 100ng/mL noggin OR 10μM SB431542 and 1μM dorsomorphin. 20ng/mL FGF2 upon appearance of rosettes Use of Insulin, NEAA, 2-mercaptoethanol
