ABSTRACT:
A stable reagent for use in a rapid and sensitive globulin estimation procedure consists of 60-70 volumes of glacial acetic acid, 1-20 volumes of monomethyl ether of ethylene glycol, 5-15 volumes of phosphoric acid, 5-15 volumes of sulfuric acid, 0.2-0.6 volumes of twenty percent glyoxylic acid in aqueous solution, and 0.4-1.2 volumes of ten pecent ferric chloride hexahydrate in aqueous solution. The reagent is far more stable, sensitive, and tolerant of water in the reaction mixture than previously known reagents used in the glyoxylic reaction.
