Product Overview
This rabbit polyclonal antibody detects C-X-C chemokine receptor type 4 (gene CXCR4) in human samples and is validated for Western blot. The predicted molecular weight is 39.7 kDa, and the supplier reports an observed band at about 50 kDa.
CXCR4 is a G protein-coupled receptor for the chemokine CXCL12 (SDF-1). It controls retention and homing of hematopoietic stem cells in the bone marrow and guides lymphocyte trafficking and embryonic cell migration. CXCR4 is also a coreceptor for T-tropic HIV-1 and is widely studied in cancer metastasis and stem cell mobilization.

|---|
Samples with a confirmed band (WB): MDA-MB-231 cells, MCF-7 cells, Jurkat cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Immunogen
Synthetic peptide from the N-terminal region of human CXCR4.
Reactivity Notes
The supplier lists reactivity with human. UniProt places C-X-C chemokine receptor type 4 in the cell membrane, cell junction, early endosome and late endosome. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
