TL;DR
A simple procedure is described for the preparation of monospecific antisera to human and mouse serum fibronectin using gelatin coupled to CNBr-activated Sepharose 4B and it is shown that this procedure could also be used to prepare antibodies to fibronECTin from other species.
Abstract
In the present paper we describe in detail a simple procedure for the preparation of monospecific antisera to human and mouse serum fibronectin. A similar procedure could also be used to prepare antibodies to fibronectin from other species. The procedure, based on the recently reported affinity of fibronectin for gelatin, essentially consists of two steps (1) Immunization of rabbits with fibronectin purified from serum by affinity chromatography using gelatin coupled to CNBr-activated Sepharose 4B. (2) Absorption of the antiserum obtained by an immunoabsorbent prepared using fibronectin-free serum proteins that remained after absorbing serum with gelatin-Sepharose. The antisera obtained were monospecific, as determined by immunoelectrophoresis and did not show any difference with respect to antisera prepared by different procedures.

By standardizing the technical conditions of the experiment it is possible to use this principle for the immunochemical determination of antigens, and the lower limit of the method was found to correspond to 0·0025 μg of antigen, and to an antigen concentrations of 1·25 μg per ml.

The findings suggest the possibility that Malignantly transformed fibroblasts lack surface fibronectin, which results in a lack of anchorage to the surrounding intercellular matrix, which could contribute to the malignant growth behavior.

Evidence concerning the reasons for these alterations and the possible functions of some of the molecules is reviewed, and particular emphasis is placed on the idea that surface molecules are associated in specific non-covalent complexes which are important for their functions.
Journal of Biological ChemistryThe Cold-insoluble Globulin of Human Plasma

The cold-insoluble globulin of human plasma has been highly purified and there was no evidence of any alteration of the electrophoretic, ultracentrifugal, or NH2-terminal characteristics of CI-globulin following thrombin treatment or heating to 56° for 5 min.
Journal of Biological ChemistryCross-linking of cold-insoluble globulin by fibrin-stabilizing factor
567 Citations1975DF Mosher
Observations suggest that CI globulin is enzymically cross-linked to one of the chains of fibrin, most likely the alpha chain, and is thus covalently incorporated into the fibr in clot, and may typify reactions also involving the fibroblast membrane protein.

Abnormal synthesis of fibronectin and other matrix components and abnormal interactions with the tissue matrix may account for several phenotypic characteristics of transformed cultured cells and for some of the malignant behavior of neoplastic cells in vivo.

A cell-type specific glycoprotein antigen from fibroblast surface appears in human plasma and serum and its appearance in the cryoprecipitate fraction of plasma is likely to be due to its affinity to cryofibrinogen evident from these experiments.

Investigation of the essential structural features of the cold-insoluble globulin of human plasma showed that it is a glycoprotein containing all of the amino acids usually found in proteins, consistent with speculation that the smaller subunit may be a catabolic intermediate arising via release of peptide material containing the COOH-terminus of a parent chain.

CIg may be important in the regulation of hepatic reticuloendothelial phagocytic activity and nonspecific systemic host defense and, in part, mediated by a deficiency or depletion of the alpha2SB glycoprotein.

Evidence is presented that fibronectin is a DNA-binding protein (at least under in vitro assay conditions) and appears to be a normal constituent of chromatin as chromatin is currently isolated from cell nuclei.
