In China, the market price of fetal bovine serum remains high, and the product quality is unstable. CB standard fetal bovine blood, as a high-quality and economical fetal bovine serum, was screen out from pregnant cows in Australian or New Zealand after 18 months of blood collection visits and repeated comparison test. Relying on the guidance of blood collection and production technology of senior experts in the United States and Australia, fetal bovine serum was processed by using cardiac puncture technology. Multiple batches of serum of this grade, Extra Grade, Premium Grade, and other imported brands of fetal bovine serum have been repeatedly tested in varieties of cells, after more than 60 days continuously cell culture and observation and value-added testing, all of which have shown good experimental results.
Fetal bovine serum is the most abundant natural medium in cell culture, which contains rich nutrients necessary for cell growth and has extremely important functions. Serum contains various amino acids, vitamins, inorganic substances, lipids and other nutrients necessary for cell growth, as well as hormones, growth factors and binding proteins that promote cell growth, such as insulin, hydrocortisone, dexamethasone, bFGF, EGF, PDGF and transferrin. In addition, serum also has the effects of detoxification, buffering, inhibition of protease activity, protecting cells from harm.
CB fetal bovine serum was collected from healthy cattle in non-epidemic areas, and was obtained through aseptic collection, mixed in batches, filtered and packaged with a 3-stage 100-nm filter, without mycoplasma, BVDV, PI3, IBR, BPV and other bovine viruses involved. The general proportion of addition is: 5-20%.
