Immunohistochemistry analysis of beta-2 Microglobulin showing staining in the cytoplasm and weak staining in the nucleus of paraffin-embedded mouse kidney tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a beta-2 Microglobulin ABfinity Recombinant Rabbit Monoclonal Antibody (701250) diluted in 3% BSA-PBS at a dilution of 1:20 for 1 hour at 37ºC in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

This antibody is predicted to react with non-human primate, mouse and rat based on sequence homology.
ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Beta-2-microglobulin is a low molecular weight protein associated with the HLA complex, and is an important cell surface structure. The amino acid sequence of Beta-2-microglobulin is homologous to the constant regions of immunoglobulin heavy and light chains, with a predominantly beta pleated sheet structure. The protein is ubiquitously expressed in the cytoplasm, and is involved in antigen processing and presentation. Beta-2-microglobulin also plays a role in TCR signaling, and downstream signaling in naïve CD8+ cells. Beta 2-microglobulin is encoded by the b2m gene located on chromosome 15.
