一般說明

L-赖氨酸是一种同聚多肽,具有两种对映体形式,L和D-赖氨酸。通过三个反应基团(羧酸以及 α 和ε胺),L-赖氨酸可以生成各种支化聚合物结构,包括树状分子、支化多聚赖氨酸和超枝化多聚赖氨酸(PLL)。 多聚-L-赖氨酸是由带正电荷的氨基酸残基组成的聚合物,每个赖氨酸残基含有一个HBr。

應用

多聚-L-赖氨酸已用于:

  • 在呼吸爆发活性测试中包被细胞附着用96孔板。
  • 包被盖玻片进行胞内结构的免疫荧光标记。
  • 在肌卫星细胞分离实验中对6孔板进行预处理。
  • 在E14神经元培养中包被细胞附着用盖玻片,以研究神经元中circRNA_01477作用的可能机制。
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

多聚‐l‐赖氨酸(PLL)是一种聚阳离子聚合物,广泛用于携带药物、基因等穿过细胞膜。 多聚-L-赖氨酸(PLL)可与阴离子化合物(如聚阴离子、核酸链和一些药物)相互作用,从而参与聚电解质复合物(PEC)的形成。
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。

成分

聚-L-赖氨酸是一种带正电荷的氨基酸聚合物,每个赖氨酸残基约有一个HBr。 氢溴酸盐可使聚-L-赖氨酸以可溶于水的结晶形式存在。 在β结构中可能会发现少量的产物,因为HBr干扰氨基与羧基或含N或O部分之间的氢键。

準備報告

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。
