CYTO-ID®长期细胞示踪试剂盒(绿色/红色)——ENZO热销产品

Enzo Life Sciences的CYTO-ID®绿色/红色长期细胞示踪试剂盒采用专有的非共价细胞标记技术,将含有疏水性脂肪链的荧光染料稳定地结合入细胞膜的脂质双分子层中。标记缓冲液对哺乳动物细胞是等渗的,不含去污剂或有机溶剂。染料对细胞没有毒性,可在细胞中保留长达96小时,并在有丝分裂时传递给子细胞。由于该染料不对细胞内的蛋白质进行共价修饰,与基于硫醇反应的氯甲基或胺反应的琥珀酰亚胺酯类荧光染料的分子探针相比,细胞正常的生理反应得到更好的保留。


也可以使用CELLESTIAL®染料进行双重标记。标记的细胞可以通过共聚焦荧光显微镜等仪器进行观察。此外,染料标记的和未标记的细胞群可通过流式细胞仪进行分析。在延长96小时的培养后,没有观察到荧光转移到相邻细胞。这与Calcein AM和BCECF AM标记形成鲜明对比,后者在生理温度下只能在存活的细胞内保留几个小时。


Enzo Life Sciences的CYTO-ID®长期细胞示踪试剂盒适用于多种应用,如追踪细胞谱系,长期细胞活力、细胞毒性、细胞粘附、细胞迁移和细胞-细胞融合研究。

 

产品特点

● 可使用各种CELLESTIAL® 荧光探针进行双重标记

● 荧光从染料标记的细胞转移到未标记的细胞的情况极少

● 适用于长期细胞存活率、细胞毒性、细胞粘附、细胞迁移和细胞间融合测定
