应用

聚-L-赖氨酸聚合物可用于促进细胞对固体底物的粘附、与甲氨蝶呤结合以增加药物转运、胰岛微囊化、细胞微囊化技术、微阵列玻片涂层和染色体制剂。 较低分子量的聚-L-赖氨酸(30000-70000)在溶液中粘度较低,但分子量较高的聚赖氨酸在每个分子中提供更多的附着位点。

生化/生理作用

聚-L-赖氨酸是一种非特异性的细胞附着因子,通过增强细胞膜负离子与培养基表面的静电相互作用,促进细胞对固体基质的粘附。 当其吸附到细胞培养表面时,聚-L-赖氨酸的作用是增加可用于细胞结合的带正电荷位点的数量。 对于可降解聚-L-赖氨酸的细胞,应采用聚-D-赖氨酸作为附着因子。

组分

聚-L-赖氨酸是一种带正电荷的氨基酸聚合物,每个赖氨酸残基大约含有一个HBr。 氢溴酸盐使得聚-L-赖氨酸以晶体形式溶于水。 由于HBr会干扰氨基和羧基之间的氢键,或含有N或O基团之间的氢键,所以其产物中可能会发现少量的β结构产物。

制备说明

本品为0.01%无菌过滤水溶液,分子量为150-300kda。涂布该溶液的载玻片应在室温下孵育5分钟并干燥。 涂覆的载玻片如能防尘,可稳定使用一年。
