A colorimetric method for the assay of streptomycin

Chemical methods for the assay of streptomycin and dihydrostretptomycin were investigated and some that have survived trial were described. Due to their inadequacies it seemed feasible to investigate the possibilities of the Vogues-Proskauer method for the assya of these antibiodies. Some modifications of the Voges-Proskauer method are rapid and simple to perform and should any of these modificaions prove adaptable for the assay of streptomycin and dihydrostreptomycin, a cheaper, simpler, and faster method of assay than any now known would be available.
