title: [Functional reaction of a fibroblast surface protein (author's transl)].
abstract: Cold-insoluble globulin (CIG) of plasma represents the soluble form of a fibroblast surface protein. As shown by affinity chromatography it is selectively adsorbed from plasma on immobilized collagen of various types. The following sequence of binding strength between CIG and collagen was evaluated by means of fractionated elution: collagen type III native less than type I native less than type I denatured. The affinity to native collagen is important for the capability of CIG to mediate the attachement of fibroplasts on collagen fibrils. In addition, CIG is a substrate of activated coagulation factor XIII which plays an important, but as yet unclarified role in wound healing.
