Western Blot and ELISA are routine, analytical lab-experiments that utilize a specific antigen-antibody interaction to detect proteins in test samples. Immunohistochemical staining (IHC) is also based on a similar principle whereby a particular interaction allows both the detection of protein(s) as well as the estimation of the gene-expression levels in tissue sections, cell smears or culture samples. abm provides high-quality chemicals and reagents needed for protein extraction, sample preparation, SDS-PAGE and chromogenic/chemoluminescent detection as well as a comprehensive range of primary and secondary antibodies.
