Specificity / Sensitivity

β2-microglobulin (D8P1H) Rabbit mAb recognizes endogenous levels of total β2-microglobulin protein.

Species Reactivity:

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val57 of human β2-microglobulin protein.

Background

β2-microglobulin (B2M) is a principal component of the Major Histocompatibility Complex (MHC) class I molecule, a ternary membrane protein complex that displays fragments derived from proteolyzed cytosolic proteins on the surface of cells for recognition by the surveillance immune system (1,2). As an integral component of the MHC class I complex, β2-microglobulin plays a critically important role in immune system function (3). It has important relevance to cancer biology research; for example, research studies have shown that nearly one-third of diffuse large B cell lymphomas contain mutations that inactivate β2-microglobulin gene function, thereby allowing tumor cells to escape immune detection (4). In addition, β2-microglobulin has been identified as an amyloid preprotein with collagen-binding affinity (5); its accumulation in osteoarthritic lesions of long-term dialysis patients is reportedly a contributing factor to the condition known as amyloid osteoarthropathy (6).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Western Blotting Image 1: β2-microglobulin (D8P1H) Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using β2-microglobulin (D8P1H) Rabbit mAb (upper) and β-Actin (DA8) Rabbit mAb #8457 (lower). DLD-1 and Daudi cell lines are negative for β2-microglobulin due to genomic deletions at the β2-microglobulin locus.

Simple WesternTM analysis of lysates (0.1 mg/mL) from HepG2 cells using β2-microglobulin (D8P1H) Rabbit mAb #12851. The virtual lane view (left) shows the target (as indicated) at 1:10 and 1:50 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:10 (blue line) and 1:50 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the JessTM Simple Western instrument from ProteinSimple, a BioTechne brand, using the 2-40 kDa separation module.
