Short Description: This B2M Competitive ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in human cell culture supernatant, serum and plasma (EDTA, citrate, heparin).
Storage Instruction: If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual.
Assay Time: 2.5h
Detection: Colormetric
Gene Symbol: B2M
Gene ID: 567
Uniprot ID: B2MG_HUMAN
Specificity: This kit recognizes Human BMG/Beta 2-MG in samples. No significant cross-reactivity or interference between Human BMG/Beta 2-MG and analogues was observed.
Sample Type: Serum, plasma and other biological fluids
Function Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Exogenously applied M.tuberculosis EsxA or EsxA-EsxB (or EsxA expressed in host) binds B2M and decreases its export to the cell surface (total protein levels do not change), probably leading to defects in class I antigen presentation.
