Polyvinyl alcohol (Mw 13000-23000, 87-89% hydrolyzed) (Synonyms:PVA (Mw 13000-23000, 87-89% hydrolyzed); Poly(Ethenol) (Mw 13000-23000, 87-89% hydrolyzed))
目录号 : KM32632 CAS No. : 9002-89-5

Polyvinyl alcohol (Mw 13000-23000, 87-89% hydrolyzed) 是分子量为 130000-23000 具有水解特性的聚乙烯醇。Polyvinyl alcohol (Mw 13000-23000, 87-89% hydrolyzed) 是由乙烯醋酸酯聚合后水解除去醋酸基团而得到聚乙烯醇。87-89% 的水解度表明很大一部分乙酸酯基团已被去除,导致 PVA 结构中产生大量羟基。不同水解度的 Polyvinyl alcohol 可用于自交联组成冷冻凝胶,被应用为生物辅料。Polyvinyl alcohol 可通过静电纺丝技术用于组织工程。Polyvinyl alcohol 可实现高细胞密度、浸润性和均匀分布,从而促进细胞间功能连接。Polyvinyl alcohol 可通过体外培养提高细胞活力。Polyvinyl alcohol 已被证明可有效抑制 Doxorubicin 诱导的骨肉瘤癌细胞。

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. 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. Polyvinyl alcohol can be used in tissue engineering by electrospinning. Polyvinyl alcohol can achieve high cellular density, infiltration, and uniform distribution, facilitating functional connections between cells. Polyvinyl alcohol can improve cell vitality through in vitro cultivation. Polyvinyl alcohol demonstrates promising inhibition of ostersarcoma cancer cells with Doxorubicin.

体外研究

Polyvinyl alcohol can enable cells to adhere and grow on PVA degraded membranes during in vitro culture, and the cells are still wrapped in PVA after 24 hours.

体内研究

Polyvinyl alcohol (0-5000 mg/kg/day, oral, 70 days) is safe and has not shown any adverse toxicological or reproductive effects on male and female SD rats.
