Isotype

Mouse IgG1

Specificity

The mouse monoclonal antibody NP4D6 reacts with an extracellular epitope of CD203c, a transmembrane ectoenzyme expressed on basophils and mast cells, and overexpressed upon their activation.

Workshop

HLDA VIII

Application

FC (QC tested), ICC

Application details

Flow cytometry: The reagent is designed for analysis of human blood cells using 20 μl reagent / 100 μl of whole blood or 10⁶ cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests. Extracellular and intracellular staining.

Reactivity

Human

Immunogen

Antigen description

CD203c, also known as ENPP-3, is integral membrane ectoenzyme (ectonucleotide pyrophosphatase/phosphodiesterase 3), that hydrolyses nucleotide triphosphates and thus modulates purinergic signaling. CD203c is expressed mainly on activated basophils and mast cells. CD203c is upregulated in response to IgE-receptor cross-linking and is overexpressed on neoplastic mast cells in patients with systemic mastocytosis. Measurement of its induced enhancement on the plasma membrane is useful for diagnostics of allergies.

Entrez Gene ID 5169

UniProt ID O14638

Flow cytometry analysis (surface staining) of human basophils in allergen-stimulated whole blood (CD203cpos/ SSClow) by anti-CD203c antibody (NP4D6).

Immunocytochemistry analysis of activated human basophil by FITC-conjugated anti-CD63 (clone MEM-259, green) and PE-conjugated anti-CD203c (clone NP4D6, red); merged signal yellow. DNA visualized by DAPI (blue).
