  • What advantages does the N21-MAX Media Supplement (Catalog # AR008) have over other neuronal stem cell supplements?

    We have performed comparison testing in-house and have found that in long term cultures (21 days), we observe better synapse marker expression.

    Additionally, one major formulation difference is that our N21 contains holo-transferrin while other supplements typically contain apo-transferrin. It is reported in the literature that holo-transferrin is preferred for neuronal cell culture. We have also tested several BSA sources to determine which is optimal for neuronal cultures.
