Albumin - Bovine Serum Albumin (BSA)
Albumin, a soluble monomeric protein, comprises about half of serum proteins. Albumin is a carrier for steroids, fatty acids, and thyroid hormones and stabilizes extracellular fluid volume. Albumin is a globular unglycosylated serum protein and is synthesized in the liver as preproalbumin. After a peptide is removed, proalbumin is released from the rough endoplasmic reticulum; it is then cleaved in the Golgi vesicles to produce secreted albumin.
Life Technologies offers bovine serum albumin conjugated to fluorescent tags, which are used in tracer studies in combination with our anti-bovine serum albumin antibodies. In addition, these bovine serum albumin (BSA) fluorescent conjugates also are used in quantitative studies of electroporation and to measure plasma in rats.
BSA increases antibody functionality and longevity and serves as both a standard in protein quantitation and a stabilizing component in DNA blunt end and replacement assays.
