Specificity / Sensitivity
β2-microglobulin (D8P1H) Rabbit mAb recognizes endogenous levels of total β2-microglobulin protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp79 of human β2-microglobulin protein.
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.
Immunohistochemical analysis of paraffin-embedded HeLa (left) and DLD-1 (right) cell pellets using β2-microglobulin (D8P1H) Rabbit mAb.
Immunohistochemical analysis of paraffin-embedded colon carcinoma using β2-microglobulin (D8P1H) Rabbit mAb in the presence of control peptide (left) or antigen-specific peptide (right).
Immunohistochemical analysis of paraffin-embedded human skin using β2-microglobulin (D8P1H) Rabbit mAb.
Flow cytometric analysis of DLD-1 cells (blue) and HeLa cells (green) using β2-microglobulin (D8P1H) Rabbit mAb. Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 647 Conjugate) #4414 was used as a secondary antibody.
Confocal immunofluorescent analysis of PANC-1 (positive, left) and DLD-1 (negative, right) cells, using β2-microglobulin (D8P1H) Rabbit mAb (green). Blue pseudocolor= DRAQ5® #4084 (fluorescent DNA dye).
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).
