Calcein, AM is a cell-permeant and non-fluorescent compound that is widely used for determining cell viability.In live cells the non-fluorescent calcein, AM is hydrolyzed by intracellular esterases into the strongly green fluorescent anion calcein. The fluorescent calcein is well-retained in the cytoplasm in live cells.Hela cells stained with AnaSpecs Calcein AM fluorescent dye (Cat# AS-89201, AS-89202, AS-89203 and AS-89204). MCF-7 cells grown in 8-well slide chamber for 2 days. Cells were washed twice before adding 1 uM Calcein AM (AnaSpec cat# AS-89202). Images acquired every 3 seconds and total elapsed time on video is 12 min.

品牌介绍
Anaspec阳离子抗菌肽是所有物种先天防御的重要组成部分。在许多生物中，包括真菌，昆虫，两栖动物和人类中，已经鉴定出100多种这些肽。这些疏水性和两亲性肽表现出抗生素，杀真菌，溶血，杀病毒和杀肿瘤活性。基于它们的结构特性，这些抗菌肽可分为三类：螺旋状肽，含有一个至几个二硫键的肽以及富含某些氨基酸（例如脯氨酸或色氨酸）的肽。这些肽大多数具有一些共同的特征，例如它们的低分子量（2-5 kDa），存在多个赖氨酸和精氨酸残基以及两亲性质。尽管尚不清楚它们杀死细菌的确切机制，但已表明导致膜渗透的肽-脂相互作用在其活性中起作用。抗生素肽的实例包括洋甘菊素，其由皮肤的皮肤分泌。非洲爪蟾 ; 人嗜中性粒细胞的防御素和人唾液中的组蛋白。天蚕素是由昆虫在感染条件下产生的。天蚕素A，B和D是紧密的同源物，由天蚕素蛾的35中发现的35-39个残基组成。
