Flow cytometric analysis of human PBMC (human peripheral blood mononuclear cell) labelling Human CD203c antibody at 1/200 (1 μg) dilution/ (Right panel) compared with a Mouse IgG1, κ Isotype Control / (left panel). Goat Anti-Mouse IgG Alexa Fluor® 647 was used as the secondary antibody. Then cells were stained with CD123 - FITC antibody separately.

Background
CD203c, also known as ectonucleotide pyrophosphatase/phosphodiesterase-3 (E-NPP3), is a type II transmembrane protein belonging to the ectonucleotide pyrophosphatase/phosphodiesterase family. It is specifically expressed on basophil-committed progenitor cells and mature basophils, and to a lesser extent on tissue mast cells. CD203c is rapidly upregulated on the cell surface upon basophil activation, such as through cross-linking of the IgE receptor, making it a valuable activation marker for these cells. It plays a role in regulating the inflammatory response by hydrolyzing ATP, which helps suppress chronic allergic inflammation. Additionally, CD203c has been identified as a potential biomarker for basophilia in diseases like chronic myeloid leukemia (CML), where its expression levels correlate with disease severity and treatment response.
