Human Serum Albumins

Human serum albumin (HSA) is the most abundant protein in human plasma with a molecular weight of 66,437 Da (based on amino acid composition). Commercial preparations contain varying degrees of post-translational modifications and genetic variants with molecular weight components mainly in the range of 66,437 to 66,600 Da

Sigma-Aldrich produces human serum albumin using a cold alcohol fractionation process derived from the traditional Cohn method as well as heat shock methods. We offer both native and recombinant versions in powder and solution forms.
