    The area, intensity, and density of PSD-95 signal are comparable to the culture grown in B27.

    I have previously used Gibco B27®, and Gem21 NeuroPlex™ for culturing of neural cells and neuronal lines. I use typical for co- culture of neurons with astrocytes and microglia. I tried your sample N21 max from R&D and it worked very well with my neuronal cells co cultures. All of these Gibco B27®, and Gem21 NeuroPlex™ and N21 max are Supplied as a 50X concentrate and are list priced at $79 for 10 ml. I would use them all interchangeably as they all worked equally well in my co culture system.

FAQs for N21-MAX Media Supplement (50X)

  • 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.
