Apoptosis is associated with the fragmentation of chromosomal DNA into approximately 180-bp nucleosome fragments. The ApopLadder Ex kit permits the selective extraction of small, fragmented DNA from apoptotic cells while minimizing chromatin contamination. This kit also supports highly sensitive detection and quantitation of fragmented DNA. Detection of fragmented DNA following extraction can be performed via a DNA fragmentation assay involving gel electrophoresis, with gel-band quantification enabled by intercalating green dye fluorescent staining. The ApopLadder Ex kit contains the necessary reagents for cell lysis, enzymatic degradation of protein and RNA, precipitation of DNA fragments, and a 6X loading dye for gel electrophoresis.

的试剂:免疫吸附剂、结合物和酶的底物。
完整的ELISA试剂盒包含以下各组分:
(1)已包被抗原或抗体的固相载体(免疫吸附剂);
(2)酶标记的抗原或抗体(结合物);
(3)酶的底物;
(4)阴性对照品和阳性对照品(定性测定中),参考标准品和控制血清(定量测定
中);
(5)结合物及标本的稀释液;
(6)洗涤液;
(7)酶反应终止液。
elisa试剂盒回收率是反应待测物在样品分析过程中的损失的程度,损失越少,回收率越高,如果作标液1PPM,就是1毫克/升,而作出标准数据为0.99毫克/升,就是说你的回收率是99%,这个与真实成分有密切的关系,说明方法的准确度。比如水中总无机氯含量测定,样品水中含有无机氯20mg/L,取100mL被测水样品,加入0.1mL浓度为10mg/mL的含无机氯标准样品,测定时忽略体积变化,如果测定出样品中无机氯为2.98mg/L,则认为回收率为99%。向左转|向右转
