| 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 |
Additional Info
| 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. |
