New highly sensitive sandwich ELISA system for soluble endoglin quantification in different biological fluids.

Soluble endoglin (sEng) is a fragment of a membrane-associated receptor (CD105) expressed on endothelial cells, mesenchymal stem cells and trophoblast cells. It is considered as a regulatory factor involved in the development of preeclampsia (PE) and cancer-associated neo-angiogenesis. The purpose of this study was to describe a new sandwich ELISA for sEng quantification.
