标题[求救]cell cytosol & membrane fraction
时间Thu Mar 27 13:33:28 2014
找到一个paper上写
"Frozen tissues were powdered at liquid nitrogen temperature and homogenized
in buffer A (5 mM TRIS, 4 mM EGTA, 2 mM EDTA, 5 mM dithothreitol, 1 mM
phenylmethyl sulfonylfluoride and EDTA-free protease inhibitor [1 tablet/10
ml]). The homogenate was centrifuged at
100,000 X g for 30 minutes ..
...
後来跟实验有做过得讨论,有做过mitochondria fraction的
觉的说用16000xg, 转1-2hr也可以, 但是量会比较少
因为超高速离心管要把体积补倒满,约12mL,
这样一下我怕浓度会太稀
请问如果改16000xg 转1-2hr 真的可行嘛?
谢谢

1F:推 asada1l:做过4小时也离不出个东西 03/27 16:30
2F:→ Invec:16000g 能把membrane离下来吗? 很怀疑 03/27 18:10
3F:推 ad1980:我做过 membrane 的,是用 floatation, sucrose gradient 04/07 15:21
4F:→ ad1980:基本上 membrane 会浮在两曾之间 04/07 15:22
5F:→ ad1980:But I used cultured cells 04/07 15:23
