Goats were immunized with ECS, Enterokinase Cleavage Site (xxxDDDDK) conjugated to KLH. Antibody was isolated by affinity chromatography using the peptide immobilized on solid support and conjugated to horseradish peroxidase (HRP). Antibody concentration was determined by extinction coefficient prior to conjugation: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG. Molar enzyme/antibody protein ratio is 4:1. By ELISA and Western blot, this antibody reacts with FLAGTM.
