Product introduction
多聚赖氨酸(D型)英文名为Poly-D-lysine,简称 PDL。本 Poly-D-lysine 为 Poly-D-lysine hydrobromide,分子式为 D-Lys-(D-Lys)n-D-Lys·xHBr,分子量为 150,000-300,000,CAS Number 27964-99-4。 本产品为已经配制好的多聚赖氨酸D型溶液,并经过滤除菌处理,可以直接稀释后用于细胞或组织培养方面的实验。本产品适用于组织学,免疫组织化学,冰冻切片,细胞涂片,原位杂交等实验中玻片的防脱片处理,以防实验操作过程中组织掉片。也可用于细胞培养,增加细胞贴壁能力。 Poly-D-lysine 和 Poly-L-lysine 都可以用于促进细胞的贴壁生长。Poly-L-lysine 可以被某些细胞所消 化并吸收,摄入过多的Poly-L-lysine会产生一定的细胞毒性。如果遇到Poly-L-lysine有细胞毒性的情况,可以考虑选购Poly-D-lysine。 使用说明: 使用多聚赖氨酸进行细胞相关包被实验,需根据不同的细胞系和应用进行包被条件的优化 1、稀释:用无菌纯化水或PBS溶液稀释多聚赖氨酸溶液至工作浓度,一般0.1mg/mL(即 0.01%),即稀释本产品50倍后配成工作液。 2、使用之前将稀释后的多聚赖氨酸溶液放置于室温下,使其温度达到室温18-26℃。 3、包被: 培养器皿(培养瓶、培养皿、培养板):将工作浓度的多聚赖氨酸溶液加入培养器皿,加入量视器皿大小而定,一般而言,能够覆盖住培养器皿的生长面即可。37℃静置2h~4h或室温下静置过夜,无菌操作。去除多聚赖氨酸,用无菌纯化水或PBS溶液洗涤培养器皿,超净台无菌风干后使用。接 种细胞前用培养液洗涤培养器皿1次,然后将细胞接种至包被好培养器皿中。 玻片:将玻片浸在工作浓度的多聚赖氨酸溶液中5分钟,增加时间不会提高包被效果。将玻片置于 60℃烘箱1小时干燥,或室温过夜干燥待用,注意无菌操作。处理过的玻片可常温存放一年。 注意事项: 1、包被之前玻片必须保持清洁,必要时用含1%HCl的70%乙醇溶液来清洗。 2、稀释过的多聚赖氨酸溶液可放在2-8℃,至少3个月内是稳定的。 3、用过的稀释液再次使用时要过滤,若出现浑浊或染菌应丢弃。 4、为了您的安全和健康,请穿实验服并戴一次性手套操作。
