CD52 Antibody, anti-human, PE, REAfinity™，130-123-972，美天旎

Clone REA164 recognizes CD52, a glycosylphosphatidylinositol (GPI)-anchored, 25–29 kDa heavily glycosylated antigen. The CD52 core peptide is only 12 amino acids long and is linked to the surface via C-terminal GPI anchor. Expression of CD52 is found on lymphocytes, monocytes, macrophages, eosinophils, and in the male reproductive tract on the epithelial cells of the epididymis and seminal vesicle. CD52 is absent in immature spermatozoa in the efferent ducts but is acquired by the sperm membrane, progressively, as they pass through the epididymis proper, where CD52 is shed into the seminal plasma by the epididymis. Though the exact role of CD52 is unclear, antibodies against CD52 elicit antibody dependent cellular and complement mediated cytolysis of the CD52 expressing lymphocytes. Owing to this, such antibodies are often used to target malignant cells. CD52 expressed on sperms and on lymphocytes are basically different glycoforms of the same core peptide.

Additional information: Clone REA164 displays negligible binding to Fc receptors.
