Instead of working with two separate peptide vials, researchers can use one combined blend for studies that require both peptide components in the same protocol
After the cells reached 80% confluence, sample preparation for western blotting was performed using lysis buffer [50 mmol/l HEPES, 50 mmol/l NaCl, 1% (v/v) Triton X-100, 10% (v/v) glycerol, 1.5 mmol/l MgCl2, 1 mmol/l EDTA, 10 mmol/l sodium pyrophosphate, 1 mmol/l Na3VO4, 100 mmol/l NaF, 30 mmol/l 2-(p-nitrophenyl) phosphate, 1 mmol/l phenylmethylsulfonyl fluoride, 10 mg/ml leupeptin and 10 mg/ml aprotinin (pH 7.4)] as previously described (39)
This verification step is particularly valuable when working with potent compounds
Its levels can decline if the body isnt getting enough selenium and vitamin C, which are important building blocks for glutathione
