CD164 is a sialylamucin that may play a key role in the hematopoietic process, promoting CD34 (+) cell adhesion while negatively regulating CD34 (+) CD38 (lo/-) cell proliferation. It regulates cord blood CD133+ cell migration through the CXCL12/CXCR4 axis and is associated with prostate cancer metastasis and bone marrow invasion. CD164 Protein, Human (HEK293, His) is the recombinant human-derived CD164 protein, expressed by HEK293 , with C-His labeled tag.
