Product Specifications

Immunogen

This monoclonal antibody was developed by immunizing mice with a synthetic peptide containing amino acids 481-497 (CINFTRVKNNQPAKYPL) of human TEM8.

Specificity

Nanda et al (2004) note a passage dependent loss of TEM8 in HUVEC suggesting that that TEM8 may be a specific marker of the endothelial cell (EC) phenotype which is lost as primary EC's age in culture and de-differentiate.

Applications for TEM8/ANTXR1 Antibody (200C1339(SB20)) - Azide and BSA Free

Application
Recommended Usage

Immunocytochemistry/ Immunofluorescence

reported in scientific literature (Matsuda (2010))

Immunohistochemistry

2-5 ug/ml

Immunohistochemistry-Paraffin

2-5 ug/ml. Use reported in scientific literature (Hotchkiss et al (2005))

Western Blot

1-3 ug/ml
Application Notes
TEM8 is observed at ~80 kDa in western blots of HUVEC cells (Hotchkiss et al, 2005) and as an 80 kDa and 85 kDa double in human colon cell lysates (Nanada et al, 2004). The size difference is thought to be due to glycosylation as a 70 kDa band was seen when cell extracts in Nanda et al (2004) were treated with a glycosidase cocktail.

Background: TEM8/ANTXR1

The Anthrax toxin receptor (ATR) was initially discovered as the tumor endothelial marker 8 (TEM8). This protein, which exists in three isoforms (36, 40, and 60 kDa), is highly expressed in tumor vessels as well as in the vasculature of developing embryos, suggesting that it may normally play a role in angiogenesis. However, it also acts as the receptor for anthrax toxin. Following the binding of this protein by the protective antigen (PA) of anthrax, PA is cleaved and heptamerizes to form the binding site for both edema factor (EF) and lethal factor (LF). This complex is then endocytosed by the cell; acidification in endosomes allows the release of EF and LF into the cytoplasm where they interfere with MAPK signaling and induce apoptosis.
