We have high level purification technique to manufacture Metallothionein by low cost. We are the manufacturer, not distributor like other companies in this website. (I think you can find them in this website).
Our company is developing a lot of raw materials. Such as Metallothionein(MT), Recombinant Hirudin, Interleukin-2(IL-2), Epidermal Growth Factor(EGF), Aprotinin, Bradford reagent, Biuret reagent, Carboxypeptidase A, Carboxypeptidase B, alpha-Chymotrypsin, Deoxyribonuc lease I, Elastase, Intestinal Trefiol Factor(ITF/TFF-3) etc. They are more than thirty. We are also marketing our self-own technology products--Lin Sir Series Cosmetics. They are the forth generation cosmetics--made by biological technique. From 2007, we have cooperated with a US company to develop anti-radiation cosmetics.
We are honesty company, hope to meet friends in this website and cooperate in furture.
