Description

Healthgen uses State-of-the-art platform called OryzHiExp, 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. The platform is a rice-specific endosperm cell-specific expression platform that focuses on the expression of animal-free products, safe recombinant proteins and peptides. We use this technique to express recombinant human serum albumin to achieve higher safety and biosafety.

Advantages

1. The chairman of Healthgen Professor Daichang.Yang is one of China's chief scientists. Professor Yang has rechieved the “Thousand Talents program” of the National Central Organization Department, "Hundred Talents Program" of the Organization Department of Hubei Province and Top 10 "Venture Eagle" entrepreneurs.

2. With years of effort, Healthgen has developed the State-of-the-Art platform called OryzHiExp, having high capacity to express no animal origin proteins and peptides in the rice endosperm cells.

3.  Healthgen Biotechnology Corp. has been committed in research of protein purification and meanwile our technology has been patented by the US Patent and Trademark Office on May 15th 2015. "A method for isolating and purifying recombinant human serum albumin from transgenic rice grain". The patent number is US9, 023,990. The purity of our rHSA is very high. Now, our rHSA purity can be as high as 99%.
