Molecular weight of BSA

What is BSA and what is the molecular weight of BSA? Albumins bind, sequester and stabilize a range of important molecules and proteins. Bovine serum albumin (BSA) is a small (~66 kDa) globular albumin protein that has been utilized in many well-cited applications. Our BSA products have been used and published in peer-reviewed articles for many applications, including cell culture, IHC, ELISA and many more. We offer a wide variety of BSA products for your research and manufacturing need The molecular weight of BSA has frequently been cited as 66,1201 or 66,2672, but it was revised in 1990 to 66,430 3 . All three values are based on amino acid sequence information available at the time of publication Based on the amino acid sequence, the molecular weight of bovine serum albumin is 66430.3 daltons, which is equivalent to 66430.3 g/mol BSA is described as a globular non-glycoprotein with a molecular weight close to 66 430. It is made of 583 amino acid residues and has 17 cystine residues (8 disulphides bridges and 1 free thiol group) ( Carter and Ho 1994 , Hirayama et al. 1990 )

The release of BSA was hardly affected by the molecular weight of the polymer. Fluorescence spectroscopy and SEC showed that the released BSA preserved its structural integrity. Microspheres were fully degradable, and the degradation time increased from ~20 days to 60 days when the HMG content decreased from 50% to 25%. Taking the degradation and release data together, it can be concluded that the release of BSA from PLHMGA microspheres is governed by degradation of the microspheres predicted protein molecular weights and the calculated protein molecular weight. According to the manufacturer, BSA had a size of 66.4 kDa. To compare their weights, both sequences were accessed on the Uniprot database (P02769 [ALBU_BOVIN] and P00004 [CYC_HORSE], respectively).

Product Description. GoldBio BSA is a highly purified, lyophilized albumin, suitable for Westerns, enzyme systems, protein standards, hybridizations and as a protease-sensitive immunoassays. It is also perfectly suitable as a nutrient in cell culture media, with low interference and backgrounds and is ideal for most standard molecular biology. The BSA molecule is made up of three homologous domains (I, II, III) which are divided into nine loops (L1-L9) by 17 disulphide bonds. The loops in each domain are made up of a sequence of large-small-large loops forming a triplet. Each domain in turn is the product of two subdomains (IA, IB, etc.). The primary structure of albumin is unusual among extracellular proteins in possessing a single. myoglobin was used for mass calibration of the mass spectrometer.
