Purified human mannose receptor from human placental tissue.
The Mannose Receptor (MR), a member of the vertebrate C-type lectin family, is a pattern recognition receptor that is involved in both innate and adaptive immunity. The 180 kDa transmembrane protein consists of 5 domains: an amino-terminal cysteine-rich region, a fibronectin type II repeat, a series of eight tandem lectin-like carbohydrate recognition domains (responsible for the recognition of mannose and fucose), a transmembrane domain, and an intracellular carboxy-terminal tail. The structure is shared by the family of multi lectin mannose receptors: the phospholipase A2-receptor, DEC 205 and the novel C-type lectin receptor (mannose receptor X). The MR recognises a wide range of gram positive and gram negative bacteria, yeasts, parasites and mycobacteria. The MR has also been shown to bind and internalize tissue-type plasminogen activator. MR's are present on monocytes and dendritic cells (DC) and are presumed to play a role in innate and adaptive immunity, the latter via processing by DC. The expression of MR as observed in immunohistology is present on tissue macrophages, dendritic cells, a subpopulation of endothelial cells, Kupffer cells and sperm cells.
Our Abpromise guarantee covers the use of ab8918 in the following tested applications.
|Flow Cyt||1/50. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.|
|WB||1/50. Detects a band of approximately 175 kDa (predicted molecular weight: 166 kDa). This antibody can be use for ligand-receptor intervention studies.|
|IHC-R||Use at an assay dependent concentration.|
|IHC-FoFr||Use at an assay dependent concentration.|
|Inhibition Assay||Use at an assay dependent concentration. Antibody 15-2 functions as an inhibitor of binding. The antibody was functionally tested by preincubation of immobilized receptor with antibody. This prevented binding of t-PA to immobilized receptor.|
|ICC/IF||Use at an assay dependent concentration.|
Frozen sections of human tonsil. ab8918 was used in a dilution of 1/25 and shows staining of endothelia of lymph vessels.
ab8918 staining Mannose Receptor in human mammary gland tissue section by Immunohistochemistry (Frozen sections). Tissue samples were fixed with 70% Ethanol and blocking for 10 minutes at RT was performed. The sample was incubated with primary antibody (1/10) for 1 hour. A HRP-conjugated mouse polyclonal to mouse IgG was used undiluted as secondary antibody.
Immunohistochemical analysis of murine uterus tissue sections, staining Mannose Receptor with ab8918.
Tissue was fixed with paraformaldehyde and blocked with 3% BSA for 30 minutes at room temperature. Samples were incubated with primary antibody (1/40 in 1% BSA) for 1.5 hours. An undiluted HRP-conjugated rabbit anti-mouse polyclonal IgG was used as the secondary antibody.
ab8918 staining Mannose Receptor in human endometriosis tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with acetone and blocked with 10% serum for 1 hour at 22°C. Samples were incubated with primary antibody (1/10 in PBS + 1% NGS) for 16 hours at 4°C. An undiluted HRP-conjugated goat anti-mouse IgG polyclonal was used as the secondary antibody.
