Methanol is available commercially in various purity grades. Commercial methanol is generally classified according to ASTM purity grades A and AA. Both grade A and grade AA purity are 99.85% methanol by weight. Grade "AA" methanol contains trace amounts of ethanol as well. Methanol for chemical use normally corresponds to Grade AA. In addition to water, typical impurities include acetone and ethanol (which are very difficult to separate by distillation). UV-vi… WebIn addition, Western blot analysis demonstrated loss of Bcl-2 and Bax protein during acetone or methanol fixation, whereas PF fixation before methanol permeabilization markedly reduced this loss. For studies on the intracellular localization of soluble or unknown types of antigen, the authors discourage the use of acetone and methanol as …
