“…Western blotting was carried out based on a previous description (Chen et al, 2008). In brief, cells were washed with ice-cold phosphate-buffered solution (PBS) twice and scraped into icecold lysis buffer (25 mM Tris/HCl (pH 7.4), 50 mM NaF, 100 mM NaCl, 1 mM sodium vanadate, 5 mM EGTA, 1 mM EDTA, 1% (v/v) Triton X-100, 10 mM sodium pyrophosphate, 1 mM benzamidine, 0.1 mM PMSF, 0.27 M sucrose, 2 M microcystin, and 0.1% (v/v) 2-mercaptoethanol).…”
