Vendor description (summary): Boster Bio Anti-beta 2 Microglobulin/B2m Antibody Picoband® catalog # A00456-2.
Biological background
Biological context: Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
Expression and localization notes: cellular localization: Secreted . Upon binding to the SLC22A17 (24p3R) receptor, it is internalized., tissue context: Detected in lung, spleen, uterus, vagina and epididymis. ..
Common research applications
- Western blotting (WB): Compare B2m levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of B2m in tissue sections, considering fixation and antigen retrieval effects.
- Immunofluorescence / ICC: Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.
- Flow cytometry: Quantify B2m-positive populations in single-cell suspensions with appropriate gating and controls.
- ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.
Notes for experimental interpretation
- Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
- Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.
Additional product notes (from provided fields)
- Specificity: No cross reactivity with other proteins.
- Background: Beta-2 microglobulin also known as B2M is a component of MHC class I molecules, which are present on all nucleated cells (excludes red blood cells). In humans, the beta-2-microglobulin protein is encoded by the B2M gene. The protein has a predominantly beta-pleated sheet structure that can form amyloid fibrils in some pathological conditions. The encoded antimicrobial protein displays antibacterial activity in amniotic fluid. A mutation in this gene has been shown to result in hypercatabolic hypoproteinemia.
- Cross reactivity: No cross-reactivity with other proteins
- Cellular localization: Secreted . Upon binding to the SLC22A17 (24p3R) receptor, it is internalized.
- Tissue details: Detected in lung, spleen, uterus, vagina and epididymis. .
