Detection of PAR1 in HT‑29 Human Cell Line by Flow Cytometry. HT-29 human colon adenocarcinoma cell line was stained with Human PAR1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3855, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0108).

PAR1 in HT‑29 Human Cell Line. PAR1 was detected in immersion fixed HT-29 human colon adenocarcinoma cell line using Goat Anti-Human PAR1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3855) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red, upper panel; Catalog # NL001) and counterstained with DAPI (blue, lower panel). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: PAR1

Human Proteinase-Activated Receptor 1 (hPAR1), also known as thrombin receptor, is a 65-70 kDa, 399 amino acid long member of the seven-transmembrane superfamily of cell-surface G protein-coupled receptors. PAR1 is activated by thrombin cleavage of its N-terminal propeptide in the extracellular domain. Human PAR1 is widely expressed in many cell types including endothelial cells, and it has been implicated in a variety of inflammatory responses. Over the regions used as immunogen, human and mouse PAR1 proteins are 58% identical in the region spanning the propeptide and extracellular domains, and 84% identical in the cytoplasmic tail.
