Endosialin/CD248/TEM1 Antibody (458606)

Endosialin/CD248 was detected in immersion fixed bEnd.3 mouse endothelioma cell line using Rat Anti-Mouse Endosialin/CD248 Monoclonal Antibody (Catalog # MAB7535) 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 (blue). Specific staining was localized to cell surfaces and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background

Endosialin, also known as CD248 and tumor endothelial marker 1 (Tem1), is a 165 kDa transmembrane O-glycosylated protein that contains one C-type lectin, one Sushi, one EGF-like domain and a mucin-like stalk in its extracellular domain (ECD). It is expressed on activated perivascular and stromal cells in embyronic and tumor neovasculature but is downregulated in quiescent vasculature. Endosialin regulates pericyte proliferation, migration, and adhesion to matrix Fibronectin and Collagens I and IV. It is also required for lymph node and spleen remodeling during immune responses. Within the ECD, mouse Endosialin shares 76% and 93% aa sequence identity with human and rat Endosialin, respectively.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
