Background Information


Human CD184, also known as CXCR4 (C-X-C chemokine receptor type 4), is a chemokine receptor expressed on a wide variety of cell types, including hematopoietic stem cells, lymphocytes, monocytes, endothelial cells, and many epithelial tissues. CD184 plays a key role in regulating cell migration, immune surveillance, and tissue organization. It is particularly important in guiding the movement and homing of hematopoietic stem and progenitor cells to the bone marrow, as well as directing immune cells to sites of inflammation or injury.

Structurally, CD184 is a member of the G protein–coupled receptor (GPCR) family. It is composed of approximately 352 amino acids and contains seven transmembrane α-helical domains, an extracellular N-terminus involved in ligand binding, and an intracellular C-terminal tail that mediates signaling through heterotrimeric G proteins. Upon ligand binding, CD184 activates intracellular signaling pathways that regulate cell migration, survival, and proliferation.

The principal ligand for CD184 is the chemokine CXCL12, also known as stromal cell–derived factor-1 (SDF-1). The CXCL12–CXCR4 axis is essential for embryonic development, particularly in the formation of the cardiovascular, hematopoietic, and nervous systems. This signaling pathway also regulates leukocyte trafficking and stem cell retention within bone marrow niches.

CD184 is implicated in several diseases. It serves as a major co-receptor for the entry of HIV-1 into target cells and is also involved in cancer progression by promoting tumor cell migration and metastasis. Because of its biological importance, CD184 is an important therapeutic target. Small-molecule antagonists such as plerixafor are used clinically to mobilize hematopoietic stem cells for transplantation, and other CXCR4 inhibitors are being investigated for cancer treatment, antiviral therapy, and inflammatory diseases.

Frequently Asked Questions


How do I determine the optimal antibody concentration/titer for my experiment?
We recommend titrating each new antibody lot on your own cell type and instrument, since optimal concentration depends on cell density, target expression level, and cytometer sensitivity. Suggested starting dilutions or test sizes (e.g., µg or µl per 10^6 cells) are provided on the product page as a starting reference point, not a fixed requirement.

Can these antibodies be used for intracellular or intranuclear staining, or only surface staining?
Intended use (surface, intracellular, or both) is specified per product, indicated under Application. The appropriate Related Protocol is linked for each product. If you need to detect both surface and intracellular markers in the same panel, confirm each antibody's compatibility with your fixation/permeabilization protocol before combining them.

What controls should I use alongside these antibodies?
Matched isotype controls (same host species, isotype, and conjugate) are available for most clones to help distinguish specific binding from background/non-specific staining and are linked on each product page. Unstained, single-color compensation, and fluorescence-minus-one (FMO) controls are also recommended, especially for multicolor panel design.

Can I combine InnoCyto Flow Cytometry antibodies into a multicolor panel?
Yes — antibodies across our catalog are designed to be panel-compatible, and conjugate options are offered specifically to support multiplexing. When building a panel, pair bright fluorophores with low-expression targets, avoid excessive spectral overlap, and confirm compensation is set up correctly for your specific fluorochrome combination. Use our Panel Builder to simplify the process.
