Polyvinyl alcohol (Mw 13000-23000, 87-89% hydrolyzed) 是分子量為 130000-23000 具有水解特性的聚乙烯醇。水解度是指原聚醋酸乙烯酯中的醋酸基水解為羥基的轉(zhuǎn)化率，Polyvinyl alcohol (Mw 13000-23000, 87-89% hydrolyzed) 則是由乙烯醋酸酯聚合后水解除去醋酸基團(tuán)而得到聚乙烯醇。87-89% 的水解度表明很大一部分乙酸酯基團(tuán)已被去除，導(dǎo)致 PVA 結(jié)構(gòu)中產(chǎn)生大量羥基。不同水解度的 Polyvinyl alcohol 可用于自交聯(lián)組成冷凍凝膠，被應(yīng)用為生物輔料。

生物活性

Polyvinyl alcohol (Mw 13000-23000, 87-89% hydrolyzed) is a polyvinyl alcohol with a molecular weight of 130000-23000 and hydrolytic properties. The degree of hydrolysis refers to the degree to which the acetate groups in the original polyvinyl acetate are converted into hydroxyl groups during the hydrolysis process. Polyvinyl alcohol (Mw 13000-23000, 87-89% hydrolyzed) is the hydrolysis and removal of acetate groups after the polymerization of ethylene acetate. And polyvinyl alcohol is obtained. A degree of hydrolysis of 87-89% indicates that a large part of the acetate groups have been removed, resulting in a large number of hydroxyl groups in the PVA structure. Polyvinyl alcohol with different degrees of hydrolysis can be used to self-crosslink to form cryogel, which can be used as biological excipient[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
