Reconstitution notes
To use as WB control, resuspend the lyophilizate in 50 µL of LDS* Sample Buffer to have a final concentration of 2 mg/ml. For reducing conditions, we recommend a final concentration of 0.1 M DTT.*Usage of SDS sample buffer is not recommended with these lyophilized lysates.
-
Notes
Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version - found here. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.
Access thousands of knockout cell lysates, generated from commonly used cancer cell lines.

Function
Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. -
Involvement in disease
Defects in B2M are the cause of hypercatabolic hypoproteinemia (HYCATHYP) [MIM:241600]. Affected individuals show marked reduction in serum concentrations of immunoglobulin and albumin, probably due to rapid degradation.
Note=Beta-2-microglobulin may adopt the fibrillar configuration of amyloid in certain pathologic states. The capacity to assemble into amyloid fibrils is concentration dependent. Persistently high beta(2)-microglobulin serum levels lead to amyloidosis in patients on long-term hemodialysis. -
Sequence similarities
Belongs to the beta-2-microglobulin family.
Contains 1 Ig-like C1-type (immunoglobulin-like) domain. -
Post-translational
modificationsGlycation of Ile-21 is observed in long-term hemodialysis patients. -
Cellular localization
Secreted. Detected in serum and urine. - Information by UniProt

Western blot: Anti-beta 2 Microglobulin antibody [EP2978Y] staining at 1/5000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab75853 was shown to bind specifically to beta 2 Microglobulin. A band was observed at 12 kDa in Wild-type A431 and HEK-293T cell lysates with no signal observed at this size in B2M (beta 2 Microglobulin) knockout A-431 cell line ab261893 (knockout cell lysate ab261702) or B2M knockout HEK-293T cell line ab266828 (knockout cell lysate ab256845). To generate this image, wild-type and B2M knockout A431 and HEK-293T cell lysates were analysed.
Nitrocellulose membranes were blocked in fluorescent western blot (TBS-based) blocking solution in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed in TBS-T, incubated with secondary antibodies Goat anti-Rabbit 800CW and Goat anti-Mouse 680RD at 1/20000 dilution for 1 h at room temperature, washed again then imaged.All lanes : Anti-beta 2 Microglobulin antibody [EP2978Y] (ab75853) at 1/5000 dilution
