Dojindo,细胞毒性 LDH 检测试剂盒-WST/2000/CK12

2022年4月25日 作者 jinpanbio
乳酸脱氢酶 (LDH) 是一种几乎存在于细胞类型中的酶,它在辅酶 NAD+ 的存在下催化乳酸氧化成丙酮酸。 一旦细胞受到压力、损伤、化学物质或细胞间信号的损害,LDH 就会迅速从细胞膜中释放出来。 因此,测量细胞释放的 LDH 量是评估细胞死亡的主要方法之一。 由于 Dojindo 的细胞毒性 LDH 检测试剂盒-WST 既不反映活细胞的活性,也不对细胞有害,它允许检测在含有活细胞和受损细胞的孔中进行。

Choose between Two ProceduresCytotoxicity LDH Assay Kit-WST can be applied with and without supernatant transferring. Please choose suitable method for your experiment.


Assay Procedure[Optimization of cell concentration][Homogeneous Assay][Non-homogeneous Assay]


Stable Working SolutionWorking Solution is stable for 6 months under refrigerated conditions. Therefore, after the preparation, Working Solution can be used as a ready-to-use solution at any time during this period.


Experimental Examples

为了在细胞毒性测定中获得准确的结果,样品通过不同的原理进行测量。 Cell Counting Kit-8(产品代码:CK04)测量活细胞中的 NADH,LDH 测定法测量死细胞中释放的 LDH。 根据这些结果,随着毒物浓度的增加,活细胞减少,死细胞增加。
