SDS-PAGE analysis of immunoprecipitate.

SDS-PAGE analysis was performed under nonreducing conditions for fibrinogen and GE and plasmic digests of fibrinogen and cross-linked fibrin immunoprecipitated with IF-123–conjugated Sepharose 4B. (A) GE digests. (B) Plasmic digests. In both panels, lanes 1 to 3 represent the applied samples and lanes 4 to 6 the bound proteins to the gels. Lanes 1 and 4, fibrinogen; lanes 2 and 5, fibrinogen digests; and lanes 3 and 6, cross-linked fibrin digests.
