Product Overview
Antibody from clone ANC5A5 binds to CD272 on the cell surface of human PBMC in Flow cytometry, and to recombinant CD272-muIg (cat #542-020) in EIA.
Human CD272 (BTLA, B and T Lymphocyte Attenuator) is a member of the Immunoglobulin superfamily and has sequence homology to PD-1 and CTLA4. It is expressed on T and B lymphocytes and other hemopoetic lineages. Engagement of this molecule by its ligand, CD270(HVEM, a TNF superfamily member) can down regulate activated T and B cell responses. CD272 levels on antigen specific CD8+ T cells have been reported to decrease in viral specific, but not melanoma specific activated lines (1). Polymorphism of the CD272 molecule has been linked to rheumatoid arthritis (3). Antibodies ANC6E9(cat #272-020) and ANC5A5(cat #372-020) each bind to a distinct epitope of CD272 and are suitable as a matched pair for EIA (see attachment).

Recombinant extracellular human CD272
Functional Activity
Antibody ANC5A5 does not block binding of Biotinylated CD270(HVEM)-muIg(cat #531-030) to CD272-muIg in EIA, but appears to enhance this interaction.
Safety & Handling

This antibody has been validated for FC, EIA. Always refer to the product datasheet for recommended dilution ranges and appropriate positive control samples for each application type.
Validated reactivity has been confirmed for Human. Cross-reactivity with additional species may exist based on sequence homology but has not been confirmed by the manufacturer. For unlisted species, we recommend running a preliminary validation experiment.
This antibody was raised in Mouse. For indirect detection (WB, IHC, IF), select an anti-Mouse secondary antibody that matches the isotype. For direct detection, check the variant selector for conjugated formats. Confirm secondary antibody compatibility before ordering.

Please refer to the storage conditions on the product label and datasheet. As a general best practice: upon receipt, aliquot into single-use volumes to minimize freeze-thaw cycling, which can progressively reduce antibody performance and lead to aggregation.
Validated reactivity covers Human samples. Performance can vary across different cell lines and tissue types depending on target antigen expression levels and epitope accessibility. We recommend verifying target expression in your specific model system using a known positive control before proceeding to experimental samples.
