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 biotin. Antibody concentration was determined by extinction coefficient prior to conjugation: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.

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, biotin-conjugated, goat anti-VSV-G antibody A190-130B used for WB at 0.04 µg/ml (1:25,000). Detection: Streptavidin-HRP (0.1 µg/ml) and chemiluminescence with an exposure time of 10 seconds.
