ILEX LIFE SCIENCES LLC BME VITAMIN 100X SOL 100 ML
PAN-Biotech BME Vitamin Solution (100x), 100 ml, Cell Culture Media Supplement. DESCRIPTION: BME Vitamin Solution is a 100x concentration of the same vitamins found in Basal Medium Eagle (BME). Amino acids are crucial for cell culture. Cells cannot synthesize essential amino acids and have to be added to cell culture, while non-essential-amino acids relieve the intracellular metabolism and help cells grow better under the same circumstances. The availability of vitamins is extremely important for the cells, since the cells usually cannot synthesize the vitamins. Vitamins act as co-factors for many enzymes and are essential for their function. The absence of vitamins in culture may lead to decrease in cell growth, cell death or loss of productivity. CONCENTRATION: 100X. LIQUID/POWDER: Liquid. STERILE: Yes. STORAGE TEMP: -20°C. MANUFACTURER: PAN-Biotech GmbH (Germany).
