beta 2-Microglobulin ELISA Kit (Human) (OKIA00054)

Description of target: 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.;Species reactivity: Human;Application: ELISA;Assay info: Assay Methodology: Quantitative Sandwich ELISA;Sensitivity: 0.822 ng/ml
