Abstract
The active principle of horse red blood cell haemolysate enhancing sulphonamide activityin vitro (HC factor) was partially purified by adsorption to DEAE-cellulose and subsequent fractionated elution. The properties of the factor, as disclosed so far, suggest that it may be a protein-containing substance of a rather high molecular weight. The HC factor counteracts the sulphonamide-antagonizing property of meat-extract, but not of peptone, of enzymic casein hydrolysate and of some known sulphonamide antagonists.
