Beta-2 Microgloblulin (B2M) Antigen >98%

Recombinant Beta-2 Microglobulin (B2M) antigen from Antibodies.com, presented as a 1 mg liquid preparation with verified purity exceeding 98% and validated for ELISA and Western Blot workflows. Beta-2 Microglobulin is the 11.8 kDa light chain component of MHC class I complexes and is widely investigated as a biomarker of renal tubular function, lymphoid malignancies, and solid tumor immune escape.

Researchers employ this purified antigen as an immunogen for antibody development, as a coating reagent in plate-based immunoassays, and as a positive control on Western Blots when probing cell lysates or serum samples. The protein is also useful in studies of antigen presentation, transplant immunology, and multiple myeloma progression, where free light chain and B2M levels are routinely measured in patient samples.

Supplied as a ready-to-dilute liquid in a single vial, the antigen supports reproducible plate coating across batches. Storage at -20°C with brief thaw-on-use handling is recommended, and aliquoting upon first use helps preserve activity across repeated freeze-thaw cycles for long-term research projects.
