Serum Beta-2 Microglobulin (B2M) levels are a reflection of cell turnover. Levels rise with fever, inflammation, and infection. Increased serum levels are also seen in B-cell malignancies and in renal failure and may indicate a worse prognosis for patients with early-stage Hodgkin's lymphoma.

Application Notes

Optimal dilution of the B2M antibody should be determined by the researcher.

1. Staining of formalin/paraffin tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 min.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.


Full length recombinant human protein was used as the immunogen for the B2M antibody.


Store the B2M antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
