Solutions of this product are not sterile and contain a preservative, ProClin, to control contamination. In theory you could sterile filter P8920 through low protein binding filters, such as PVDF or PES. Sterile filtering will not remove the ProClin from P8920. Live cells should not be exposed to ProClin, as ProClin interrupts the Krebs cycle at 4 different sites. It would be best to purchase the powder as P1524 and then sterile filter after the solution has been prepared.

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
该产品以0.10％（w/v）水溶液形式提供的。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。 涂覆的玻片在免收灰尘的保护下可稳定一年。

Hello! How many microscopy slides can I adhesive for every 100 milliliters of this solution( Poli-L- Lisine),? Gratitude!
1 answer-
The number of slides that may be coated is dependent upon the surface area. The general use instructions recommend using 0.5 - 1.0 mL per 25 cm2 coating area - the 25 cm2 value is based on a T-25 tissue culture flask. A standard microscope slide has an approximate area of 1.3 cm2.
Please see the link below to review the product datasheet which included a general protocol for coating: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/784/704/p6407pis.pdf

Is Product P8920, Poly-L-lysine solution, recommended for cell culture use?
1 answer-
No, the product contain 0.01% thimerosal as a preservative. For cell culture use, product P4832 is recommended. This solution has the same molecular weight as P8920 but contains no preservative. P4832 is sterile filtered and is considered suitable for cell culture use.

What are the recommended uses for Product P8920, Poly-L-lysine solution?
1 answer-
P8920 was developed for use in coating slides intended for use in either histology or immunohistochemistry. Poly-L-lysine is preferred for uses such as silver staining procedures that require an alkaline pH. Silane coated slides may be more effective is a low pH is required.
