Description: This MR6F3 antibody recognizes mouse CD206 also known as Macrophage Mannose Receptor (MMR) or Mannose Receptor C, Type 1 (MRC1). CD206 is a 175-kDa, type 1 integral membrane glycoprotein receptor that is present in macrophages, some dendritic cells, as well as liver and lymphoid endothelial cells. CD206 belongs to the C-type lectin family. Extracellular regions of CD206 include an N-terminal cysteine-rich (CR) domain that binds sulfated glycoproteins, a fibronectin II (FNII) domain that binds collagens, and eight carbohydrate recognition domains (CRDs) that bind sugars like mannose and fucose with high affinity. CD206 mediates phagocytic and endocytic uptake of fungal, bacterial, protozoan and viral antigens, and plays an important role in immune defense and immune regulation. A soluble form of CD206 is generated by cleavage of the full-length protein, and it can be detected in in vitro macrophage cell culture supernatants and in mouse serum. CD206 is considered to be one of the markers of M2 macrophages. Factors inducing its expression include: IL-4, IL-13, M-CSF, IL-6, IL-10, and glucocorticoids, while TNF-alpha, IFN-gamma, TGF-beta, and LPS have been reported to down-regulate expression of CD206. It has been demonstrated that only a small fraction of CD206 is present at the cell surface, therefore, intracellular staining is recommended.

Applications Reported: This MR6F3 antibody has been reported for use in flow cytometric analysis, and intracellular staining followed by flow cytometric analysis. Applications Tested: This MR6F3 antibody has been tested by intracellular staining and flow cytometric analysis of mouse resident peritoneal exudate cells using the Intracellular Fixation & Permeabilization Buffer Set (cat. 88-8824) and protocol. This can be used at less than or equal to 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically. Excitation: 488-561 nm; Emission: 775 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 μm post-manufacturing filtered. Mannose receptor, also know as CD206, is a 175kDa transmembrane protein belonging to the group of pattern recognition receptors. CD206 is predomitly expressed in tissue macrophages and dentritic cells and can also be found in a subpopulation of endothelial cells and sperm cells. CD206 is thought to play a role in the innate and adaptive immune response.
