ABSTRACT:
Glutamic oxaloacetic transaminase and glutamic pyruvic transaminase are determined using granular water-soluble substantially anhydrous, storage stable reagent formulations comprising a nitrogen-containing polyoxyalkylene nonionic surfactant obtained by the sequential reaction of ethylene diamine with propylene oxide and ethylene oxide in the presence of a catalyst. The surfactant contains, polyoxypropylene chains having an average molecular weight of between about 750 and about 6,750 and polyoxyethylene chains constituting between about 10 and about 80 weight percent of the surfactant. The surfactant has an advantageous effect upon granulation, dissolution and storage stability of the anhydrous reagent formulations, and is effective for solubilizing proteins.
