This monoclonal antibody was developed by immunizing mice with a synthetic peptide containing amino acids 481-497 (CINFTRVKNNQPAKYPL) of human TEM8. Percent identity by BLAST analysis: Human, Gorilla, Gibbon, Monkey, Marmoset, Dog, Panda, Rabbit (100%); Mouse, Rat, Bat, Elephant, Pig (94%); Horse, Opossum (88%).
TEM8 is observed at ~80 kD in western blots of HUVEC cells (Hotchkiss et al, 2005) and as an 80 kD and 85 kD double in human colon cell lysates (Nanada et al, 2004). The size difference is thought to be due to glycosylation as a 70 kD band was seen when cell extracts in Nanda et al (2004) were treated with a glycosidase cocktail. 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.
