|Detection of GPVI in Mouse platelets by Flow Cytometry. Mouse platelets were stained with Rat Anti-Mouse GPVI Monoclonal Antibody (Catalog # MAB6758, filled histogram) or isotype control antibody (Catalog # MAB005, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113).|
|GPVI in Mouse Platelets. GPVI was detected in immersion fixed adult mouse platelets using Rat Anti-Mouse GPVI Monoclonal Antibody (Catalog # MAB6758) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI. Specific staining was localized to cell surfaces and cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.|
GPVI (Platelet Glycoprotein VI; also glycoprotein 5) is a member of the Ig superfamily. It is found on platelets and megakaryocytes, and serves as the main collagen receptor on platelets. Following exposure to subendothelial connective tissue, GPVI binds to a Gly-Pro-(hydroxy)Pro motif on collagen and generates a noncovalent membrane signaling complex with FcR gamma -chain. This interaction is stabilized by Integrin alpha 2 beta 1, followed by activation of PLC gamma 2 with clot initiation. Mature mouse GPVI is a 292 amino acid (aa) type I transmembrane protein. It possesses a 244 aa extracellular region (aa 22-265) that contains two C2-type Ig-like domains (aa 27-197)and two potential glycosylation sites, plus a 37 aa cytoplasmic tail (aa 287-313). There is one potential splice form that shows a deletion of aa 224-240. Over aa 24-265, mouse GPVI shares 70% and 86% aa identity with human and rat GPVI, respectively.
