The effect of commonly used extracting media on the allergenic composition of cat fur extract

Extracts of cat fur prepared in 50% glycero-saline and Coca's solution were found to be very similar in biological activity and protein composition when measured by RAST and by analytical isoelectricfocussing, respectively. Pyridinated cat fur extracts were found to differ significantly from the Coca's and glycero-saline extract by these techniques.
