Human serum albumin is the most abundant protein in human plasma. It can transport hormones, lipds and other molecules and maintain osmotic pressure. Animal free rHSA is a recombinant human serum derived from rice grains, and doesn't contain any animal component, which is much safer than plasma derived HSA.

Human serum albumin is derived from human plasma, which is collected from different human bodies. So we cannot guarantee the stability of human serum albumin from different batches. Because of this, it is difficult to apply to large-scale application in vaccine production and cell culture. However, Healthgen uses State-of-the-art platform, having high capacity to express proteins and peptides in the rice grain. The platform uses rice endosperm cells as a bioreactor to specifically and highly express various recombinant proteins and small peptides. By using homozygous rice as the raw material, with the world's top production process, Healthgen can maximize the stability of albumin batches to meet the needs of industrial production.
