[Characterization of a serum protein with selective affinity for denatured collagen (author's transl)]

A protein known as antigelatin factor (AGF) was isolated from human serum by affinity chromatography with immobilized denatured collagen. In biochemical and immunological assays AGF showed specificity to denatured, but not to native collagen of the types I, II and III. A close relationship to Cell Attachment Protein and Cold Insoluble Globulin was found in comparative studies.
