The pellets remaining after the second centrifugation were washed with buffer-1 for 15 min and centrifuged at 15,000 g for 10 min, and the resulting pellets were incubated with buffer-2 [20 mM HEPES/KOH (pH 7.8), 1.5 mM MgCl 2 , 420 mM NaCl, 0.2 mM EDTA, 25% glycerol, 0.5 mM dithiothreitol, 0.2 mM phenylmethylsulfonyl fluoride, and 1 mM Na 3 VO 4 ] for 20 min
Research-grade somatropin follows the same physical rules but relies on general protein behavior rather than regulatory validation
