rHSA:recombinant human serum albumin

rHSA is a 10% or 20% solution without any animal or human derived ingredients involved in its manufacture. This eliminates concerns about the possible contamination of adventitious agents of animal or human origin, such as viruses or other infectious agents. So rHSA is ideally suited for media development, optimization or supplementation and is a perfect substitute for human serum albumin in circumstances where animal-free conditions are required.

We have been devoted to the research and development of recombinant HSA since 1997. We have established a high expression level system for rHSA in Yeast. The purification patent of rHSA was granted in 13 countries. Structure equivalence between rHSA and HSA has been demonstrated.
