聚-D-赖氨酸氢溴酸盐是一种带正电荷的合成聚氨基酸,每个赖氨酸单元有一个 HBr。它是一种可溶于水的结晶固体。聚-D-赖氨酸氢溴酸盐被广泛用作涂层,以增强细胞对塑料制品和玻璃表面的附着和粘附。这种聚阳离子对酶降解具有抗性,并已用于培养多种细胞类型。聚-D-赖氨酸的其他应用包括与活性分子结合以提高活性、逐层沉积技术以及与核酸复合以表达基因。对于细胞培养应用,聚-D-赖氨酸氢溴酸盐与建议分子量大于 30,000 Da。聚-D-赖氨酸氢溴酸盐 (MW=52,000 Da) 更易于使用,因为它在溶液中的粘度较低,但是具有较高分子量 (MW=84,000 Da) 的聚-D-赖氨酸氢溴酸盐每个聚合物具有更多的附着位点链可供细胞使用。聚-D-赖氨酸氢溴酸盐和聚-L-赖氨酸氢溴酸盐都可以用作涂层基质,但是某些细胞会消化聚-L-赖氨酸氢溴酸盐。在这种情况下,作为附着因子的多聚-D-赖氨酸是防止细胞因过度摄取 L-赖氨酸而破坏细胞所必需的。我们的多聚-D-赖氨酸氢溴酸盐已通过透析纯化,在 0.2 微米上无菌过滤,冻干, 并存储在 Ar 下。

Poly-D-lysine hydrobromide is a positively charged synthetic polyamino acid having one HBr per lysine unit. It is a crystalline solid soluble in water. Poly-D-lysine hydrobromide is widely used as a coating to enhance cell attachment and adhesion to both plasticware and glass surfaces. This polycation is resistant to enzymatic degradation and has been used to culture a wide variety of cell types. Other applications for poly-D-lysine include the conjugation to active molecules for improved activities, the layer-by-layer deposition techniques, and the complexation with nucleic acids for gene expression.For cell culture applications, poly-D-lysine hydrobromide with a molecular weight greater than 30,000 Da is recommended. The poly-D-lysine hydrobromide (MW=52,000 Da) is easier to use because it is less viscous in solution, however the poly-D-lysine hydrobromide with an higher molecular weight (MW=84,000 Da) has more attachement sites per polymer chain available to the cells. Both poly-D-lysine hydrobromide and poly-L-lysine hydrobromide can be used as a coating substrate, however certain cells digest poly-L-lysine hydrobromide. In this case, poly-D-lysine, as the attachment factor, is necessary to prevent cell disruption by excessive uptake of L-lysine.Our poly-D-lysine hydrobromide has been purified by dialysis, sterile-filtered on 0.2um, lyophilized, and stored under Ar.
