Fibrinogen is fixative resistant.

Background
Fibrinogen is a 340 kD multisubunit glycoprotein present in plasma and tissue of all classes of vertebrates. It has a variety of physiologically important functions, most of which, if not all, are assigned to certain structures of fibrin including double-stranded fibrin protofibrils and highly crosslinked fibrin networks (Shafer & Higgins, 1988; Mosessan 1997). Its role in hemostasis and thrombosis has been extensively studied (Henschen, 1983; Mosessan, 1992; Blomback, 1996; Gaffney, 1997).

Applications
Diagnostic applications of fibrinogen are largely limited to the identification of fibrinogen deposition and breakdown products in glomerular diseases (Dowling 1993).
