一般描述

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。

应用

  • 聚-L-赖氨酸涂覆的玻璃盖玻片已用于对用于扫描电子显微镜的样本进行封片。
  • 聚-L-赖氨酸涂覆的孔用于在电极上对PC-12细胞进行捕获。
  • 聚-L-赖氨酸涂覆的硼硅酸盐玻片用于接种病毒载体转导的细胞。
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。

制备说明

该产品是以溶于水的0.01%无菌过滤溶液形式提供的。用该溶液进行涂覆的玻片应当随后进行一步5分钟的孵育并在室温对其进行干燥。 涂覆的玻片在免受灰尘的保护下可稳定一年。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the concentration of Product P4707, Poly-L-Lysine solution?

    This product is supplied as a 0.01% w/v solution.

  4. What molecular weight Poly-L-Lysine product should I choose?

    The lower molecular weight poly-L-lysine (30-70 kDa) is easier to use because it is less viscous in solution, but the higher molecular weight poly-L-lysine (>300 kDa) provides more attachment sites per molecule. The mid-range product has a molecular weight range of 70-150 kDa.

  5. Should I use Poly-L-Lysine or Poly-D-Lysine?

    Certain cells secrete proteases, which can digest poly-L-lysine. For those cell types, poly-D-lysine should be used.

  6. What is the protocol for using Product P4707, Poly-L-Lysine solution, to coat slides?

    For coating slides with poly-L-lysine, in general, it is recommended to use a 0.01% (w/v) solution. After a 5 minute incubation, the excess solution is removed and the slides are dried at room temperature or in an oven at gentle heat.

  7. What is the protocol for using Product P4707, Poly-L-Lysine solution, to coat tissue culture plasticware?

    A solution of 0.1 mg/mL is prepared; 0.5 mL of that solution is aseptically transferred to a non-tissue culture treated 25 square cm flask. The flask is gently rocked to evenly coat the surface. After five minutes, the excess solution is removed and the surface is thoroughly rinsed with sterile water and allowed to dry for several hours.

  8. How can I sterilize slides coated with Product P4707, Poly-L-Lysine solution?

    Poly-L-Lysine coated slides can be exposed to UV light overnight for sterilization.

  9. How should I dilute Product P4707, Poly-L-Lysine solution?

    For coating slides with poly-L-lysine, in general, it is recommended to use a 0.01% (w/v) solution.  However, if your protocol requires a more dilute solution, you can add sterile water or sterile buffer like Phosphate Buffered Saline.

  10. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
