title: Polypeptide fluoroacetate derivatives. Synthesis and 19F n.m.r.
abstract: The synthesis and characterization of monofluoroacetyl (MFAc) functionalized haptens are described. These were covalently bound to polypeptide carriers (bovine serum albumin and poly-D-lysine) by primary amine/succinimide ester or primary amine/acid chloride coupling. Epitopic densities of the resulting antigens were determined by both 19F n.m.r. and picryl sulfonic acid assays. 19F n.m.r. experiments defining the stability of MFAc ester and amide linkages as a function of media (including in vitro), time, and temperature are presented. These results indicate that MFAc functionalized antigens are well suited for further immunologic studies.
