特異性：This item recognises bovine albumin (BSA), a soluble protein which constitutes approximately one half of blood serum protein. BSA functions primarily as a carrier protein for steroids, fatty acids, and thyroid hormones and plays a role in stabilizing extracellular fluid volume. BSA is synthesized in the liver as preproalbumin, which has an N-terminal peptide removed before it is released by the rough endoplasmic reticulum as proalbumin. In turn, proalbumin is cleaved in the Golgi vesicles to produce albumin, which is secreted into the blood stream. BSA is used as a nutrient in cell cultures, as an enzyme stabilizer during DNA digestion, and as a diluent or blocking agent in immunohistochemistry and ELISAs.
