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.

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
