Recombinant Human Serum Albumin (rHSA) Protein - Excipient-Grade
rHSA is a high-purity, excipient-grade recombinant human serum albumin (rHSA) produced in Oryza sativa (rice endosperm). Developed as a superior alternative to bovine serum albumin (BSA), rHSA is animal-free, virus-free, and engineered for unmatched quality and consistency in sensitive applications.
As the most abundant protein in human plasma, albumin plays a vital role in osmotic regulation, pH buffering, and molecular transport. rHSA delivers these same physiological functions with enhanced safety and reproducibility, without the risks associated with animal-derived products. Compared with fetal bovine serum (FBS), bovine serum albumin (BSA), and plasma-derived albumin (pHSA), plant-derived HSA has higher purity and better batch stability.

The protein appears at around 55 kDa on the gel, though its predicted molecular weight is 66.5 kDa. This variation is common, as SDS-PAGE migration can be influenced by protein folding, modifications, or other factors, leading to differences between the experimental and theoretical sizes
