Our high affinity Horse Anti-Mouse IgG Antibody is purified by affinity chromatography and adsorbed to remove any cross-reactivities that are likely to interfere with specific labeling. This antibody is then cross-linked with the highest specific activity alkaline phosphatase. A proprietary procedure for conjugation allows the maximum preservation of enzyme activity and antibody specificity. This antibody is subjected to rigorous quality control assays and can be used for tissue staining, ELISAs, and blots.
