Detection of Xg in Human Erythrocytes by Flow Cytometry. Human blood erythrocytes were stained with Goat Anti-Human Xg Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF3699, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0107).

Xg is a 26 kDa, type I integral membrane glycoprotein which belongs to the CD99 family. It is found in erythrocytes and is responsible for the XG blood group system. Its presence or absence determines Xg(a+) and Xg(a-) red cells. XG transcription is tied to CD99 transcription, although the two related molecules do not associate on the cell surface.
