Goats were immunized with AU1 (DTYRYI) conjugated to KLH. Antibody was isolated by affinity chromatography using the peptide immobilized on solid support. Antibody concentration was determined by extinction coefficient: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.
2 - 8°C
Detection of AU1-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, goat anti-AU1 antibody A190-124A used for WB at 0.2 µg/ml (1:5,000). Detection: Chemiluminescence with an exposure time of 30 seconds.
