谢谢老师回复,我看了下试剂网站说明,确实是biolegend的计数微球,Precision Count Beads™ are designed for counting the absolute number of cells in a complex mix population and other particles by flow cytometry. Precision Count Beads™ are excited by a variety of lasers including violet (405nm), blue (488nm), yellow/green (562nm), and red (633nm)。按照您最早的回复,建议的workflow是不是应该这样:1.从孔板吸取全部细胞转移至流式管 离心去上清 重悬 2. 流式染色 3.洗去游离抗体,100ulPBS重悬细胞 4.加入100ul混匀的beads(说明书推荐每个样本100ul) 5.流式上机 6.根据流式收取的cells counts 和 beads counts,已知微球密度,所以能计算出细胞悬液的密度,再乘以原先孔板的细胞悬液体积,即为原先孔板中细胞的绝对数量 |
