In the present paper we describe in detail a simple peocedure for the preparation of monosopecific 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. |
