Detection of CD177 in Human Lymphocytes by Flow Cytometry.
Human peripheral blood lymphocytes were stained with Goat Anti-Human CD177 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3505, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0107).

CD177 is a polymorphic gene in the leukocyte antigen (Ly6) uPAR superfamily. It encodes at least two alleles of the neutrophilic membrane protein PRV1 (Polycythemic Rubra Vera protein 1) and NB1 (also named HNA-2a) that are glycosyl-phosphotidylinositol (GP1) anchored proteins of 58‑64 kDa. CD177 has two highly homologous cysteine-rich uPAR/Ly6 domains. The mRNA levels of CD177 is elevated under conditions where neutrophil counts are increased and is a useful marker for polycythemic vera. Mature human and mouse CD177 share 43% amino acid sequence identity. CD177 is expressed on the surface of neutrophils through a glycosylphosphatidylinositol (GPI) anchor (1-3).
