Scientific Background
Human CD272 (BTLA, B and T Lymphocyte Attenuator) is a member of the Immunoglobulin superfamily and has homology to CD152(CTLA-4). Engagement of BTLA by its co receptor CD270 (HVEM, a TNF superfamily member) can down regulate activated T and B cell responses. BTLA levels on antigen specific CD8+ T cells have been reported to decrease in viral specific, but not melanoma specific activated lines (1).

This protein was expressed in CHO Cells cells. Mammalian expression is critical for this Fc fusion protein because it ensures proper glycosylation and tertiary folding of the extracellular immunoglobulin-like domains, preserving native receptor-binding activity.
Recombinant hCD272(BTLA)-muIg has been validated for: ELISA. It is produced as a Murine IgG Fc Fusion (muIg), making it suitable as a blocking reagent, binding standard, or functional stimulant/inhibitor in immunology assays.
Recommended storage: Store at 2 - 5°C. Freeze/Thawing is not recommended.. Formulation: 50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 0.5% Gentamicin sulfate. Avoid repeated freeze-thaw cycles. If long-term storage is needed, aliquot upon first use.
Species reactivity includes: human. Cross-reactivity was confirmed by functional binding assays (e.g., ELISA and/or FACS) against cells or recombinant proteins from the indicated species.
Available formats include: Unconjugated. Conjugated forms are ready-to-use without secondary detection reagents for flow cytometry. Unconjugated (purified) forms can be used with anti-Fc secondary antibodies in ELISA.
