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?
本人对软骨石蜡切片做了MMP-13的免疫组化染色,首次做,无法判断染色部位,请各位帮忙看一下
(2)另一方面,使抗原抗体结合更稳定。一般不需要,但对表达较弱的抗原可能有用,4度和37度时分子运动方式不同,前者分子碰撞机率和运动速度小于后者,后者结合更快,但敏感性也提高了并易造成非特异染色。
(3)其实,我更赞同后一种说法,因为我尝试把肝脏或睾丸片子从4度过夜拿出后,直接用PBS洗没发生过脱片现象。事实胜于雄辩!
