Short Description : | This B2M Competitive ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in human serum, plasma and other biological fluids. |
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. |
