Scientific Background
Human CD304 (neuropilin, NRP, NP1, BDCA-4) is a 140 kD type I glycoprotein expressed by a variety of tissue types,including Treg, follicular TH, neurons, Dendritic cells, and Endothelial cells. Its ligands include VEGF165 and Semaphorin family members. It is a reliable marker for human BCP-ALL1. Soluble CD304 has been used to slow progression of murine AML 2. CD304-muIg runs as a dimer in SDS-PAGE with a molecular weight of approximately 200 kD.

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 hCD304-muIg has been validated for: ELISA, Flow Cytometry. 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.
