B-27 Supplement XenoFree Minus Vitamin A is based on the classic B-27 Supplement formulation and contains no animal-derived components at the primary component level. The absence of vitamin A (retinyl acetate) makes this formulation ideal for the cultivation of neural progenitor and stem cells, either as neurospheres in suspension or in adherent monolayer culture, without inducing differentiation.
