Do I need additional supplements when working with PromoCell growth media? Do I have to add extra FCS?

After addition of the SupplementMix or SupplementPack to our basal medium, you obtain the complete growth medium. No further supplementation with serum or growth factors is required. Please note: Our media do not contain antibiotics. If you wish to use antibiotics you can add penicillin/streptomycin or gentamicin/amphotericin B at standard concentrations. Addition of antibiotics can however reduce the doubling time of the cells up to 30-40%.
