cell lysis buffer

[Arne Mueller]

Dear Sabine,
I use the following buffer:

50 mM Hepes-KOH, pH 7,4
2 mM EDTA
0,25 M Sucrose

collect the cells with a "rubber-scraper" and homogenize the cells with
10-20 strokes with a 22G-gauge (the number of strokes depends on the
cell type, control it via Trypan Blue staining).
the cells will be lyzed, but transmembrane- and membrane associated
proteins will stay where they are supposed to be.

Bye, Ina
