Abstract

USING the technique originated by Sanger1 for the determination of end-groups in proteins by reaction with dinitrofluorbenzene, no free α-amino- or imino-groups have been detected in ox hide collagen2, even when the equivalent of 2–3 gm. dinitrophenyl-collagen was placed on the silica gel columns.
