Goats were immunized with VSV-G (YTDIEMNRLGK) 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.

Detection of VSV-G-tagged Protein by western blot. Samples: 200, 100, or 50 ng of E. coli whole cell lysate expressing a multi-tag fusion protein. Antibodies: Affinity-purified, HRP-conjugated, goat anti-VSV-G antibody A190-130P used for WB at 0.04 µg/ml (1:25,000). Detection: Chemiluminescence with an exposure time of 30 seconds.
