    rAAT Alpha One Antitrypsin Human Recombinant Protein Protecting Cell Digestion

    rAAT Alpha One Antitrypsin Human Recombinant Protein Protecting Cell Digestion ​


    Trypsin can selectively hydrolyze the protein chain composed of the carboxyl group of lysine or arginine, which can digest and denature the protein. The Alpha-1 anti-trypsin, also known as protease inhibitors, can effectively inhibit the trypsin activity, prevents the sticky protein from being decomposed by trypsin during cell growth and thus prevent digestion.

    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 recombinant Alpha-1 Antitrypsin (rAAT) has excellent batch consistency. Using self-pollination rice as the bioreactor to express the rAAT with the world's advanced facility and top production proceeding to extract and purify the rAAT, Healthgen can ensure the excellent consistency of rAAT from different batches.

    4. The rice endosperm specific expression platform is easy to be large-scale. The rice endosperm has the protein body, which can keeps proteins stability and bioactivity. At present, the production capacity is almost 1 kg / year.

    Supplemental Description

    Recombinant Alpha 1 Antitrypsin (AAT) is a serine protease inhibitor. It protects tissues from enzymes of inflammatory cells, especially neutrophil elastase. If it is deficiency, neutrophil elastase is free to break down elastin, which contributes to the elasticity of the lungs, resulting in respiratory complications such as emphysema, or COPD (chronic obstructive pulmonary disease) in adults and cirrhosis in adults or children. OsrAAT is derived from rice grain, which contains 384 amino acids with a molecular weight of 43.1kD.
