The CellAmp Direct RNA Prep Kit for RT-PCR (qPCR) is for preparation of templates used in one- and two-step real-time RT-PCR, utilizing a simple method of extraction directly from cultured animal cells in 96 well-plates or other vessels. It is possible to prepare templates for real-time PCR from cultured animal cells in approximately 10 minutes.

Using this kit along with a one-step real-time RT-PCR kit (such as the One Step TB Green Ex Taq qRT-PCR kit) allows gene expression analysis to be performed in approximately two hours. Templates can be prepared directly from small quantities of animal cells, which is useful for analysis of a gene expression profile and does not influence the high sensitivity of real-time RT-PCR. Genomic DNA can be removed efficiently using this kit, making it a powerful tool for expression analysis of genes for which primers can"t be designed on both ends an exon junction, or genes expressed at low levels.

Bone Mesenchymal Stem Cells 作为一个细胞群体，还没有发现有特定细胞表面marker. 对于那些可以代表自我更新和分化的marker, 也不清楚到底要发现哪一个的表达才能确定该细胞就是BMSC。
目前常用的方法，就是采用培养，colony-forming unit-fibroblasts (CFU-F)这个方法。一般BMSC可以24-48小时贴壁。
流式细胞计数，比如STRO-1，但是一般认为STRO-1阳性的细胞更趋向于造血干细胞，和BMSC简单区别还不是很清楚。
这里有个培养分化的产品

有没有朋友使用碧云天的细胞衰老β-半乳糖苷酶染色试剂盒做过细胞衰老，本人小白，求相关细胞处理的过程及数据分析方法。贴壁细胞六孔板需要接种多少，染色后怎样计数进行数据处理。谢谢啦！

下面的这段话是图注，图注的意思我明白，但是我想知道merge后的图看什么颜色的荧光，蓝色是细胞核，红色是lysosome(位于胞质），绿色是AMPKβ2，该实验是想观察AMPKβ2是否转位到lysosome上了，如果确实发生了AMPKβ2转位到lysosome上，那么merge后是红色与绿色融合在一起，是吗？融合在一起发什么颜色的光了？
