CD164 Protein, a sialomucin, potentially plays a pivotal role in hematopoiesis, facilitating CD34+ cell adhesion while negatively regulating CD34+ cell proliferation[1]. CD164 Protein, Cynomolgus (HEK293, Fc) is the recombinant cynomolgus-derived CD164 protein, expressed by HEK293 , with C-hFc labeled tag.
