Panexin CD: Serum Replacement with Chemically-Defined Components. QUANTITY: 100 ml. MANUFACTURED BY: Pan-Biotech (Germany). STORAGE: -20 degrees Celsius. DESCRIPTION: PAN-Biotech Panexin CD is a chemically defined, xeno-free serum replacement for the cultivation of adherent and non-adherent cells under serum-free culture conditions or to significantly reduce the amount of serum in cell culture. It supports the growth of many cell types in an optimum manner without any extra handling compared to serum. Panexin CD is animal-free and contains recombinant proteins, lipids, salts, amino acids, trace elements, hormones and a 3-dimensional substrate release system in an optimized formulation. It contains no growth factors, undefined hydrolysates or peptones. Compared to other serum replacements, it contains only chemically defined components. Due to its very defined character, lot testing is not necessary allowing for high reproducibility and simplified downstream processing.
