Background Information


Mouse CD206, also known as the mannose receptor (MRC1), is a type I transmembrane C-type lectin receptor expressed predominantly on macrophages, immature dendritic cells, and selected endothelial cells. It functions as a pattern-recognition and scavenger receptor, contributing to innate immune surveillance, endocytosis, phagocytosis, and clearance of endogenous and microbial glycoproteins. CD206 also facilitates antigen uptake and trafficking to intracellular compartments, thereby potentially influencing antigen processing and presentation. The mouse Mrc1 gene encodes a protein that is orthologous to human MRC1/CD206.


CD206 is a large glycoprotein containing a short cytoplasmic tail, a single transmembrane domain, and a large extracellular region. The extracellular portion comprises an N-terminal cysteine-rich (CR) domain, a fibronectin type II (FNII) domain, and eight C-type lectin-like domains (CTLDs). CTLD4 and CTLD5 provide most of the carbohydrate-binding activity. CD206 recognizes glycans containing terminal mannose, fucose, and N-acetylglucosamine (GlcNAc), generally through calcium-dependent interactions. The CR domain additionally recognizes sulfated glycans, while the FNII domain can bind collagen-related structures.


CD206 participates in host defense by recognizing mannose-rich structures on microorganisms, including fungi, mycobacteria, and certain viruses. However, some pathogens can exploit CD206-mediated uptake to enter macrophages or alter immune responses. Dysregulated CD206-positive macrophage activity has also been associated with chronic inflammation, tissue remodeling, fibrosis, infection, and tumor-associated macrophage biology. Mouse studies further indicate that MRC1 influences systemic inflammatory responses and susceptibility to severe inflammatory conditions such as sepsis.


Therapeutically, CD206 is attractive primarily as a macrophage-targeting receptor rather than simply a receptor to block. Mannosylated nanoparticles, proteins, antibodies, and drug-delivery systems can exploit CD206-mediated endocytosis to selectively deliver therapeutic or imaging cargo to CD206-positive macrophages. This strategy is being investigated in cancer, infectious diseases, inflammatory disorders, and lysosomal storage diseases. CD206 therefore represents both a useful macrophage biomarker and a promising target for targeted drug delivery.

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.
