Human Endoglin (CD105) ELISA Kit

This Human Endoglin (CD105) ELISA Kit from Innovative Research is intended for quantitative detection of human CD105 in cell culture supernates, cell lysates, serum and plasma (heparin, EDTA). Strip well format. Reagents for up to 96 tests.

This human CD105 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for CD105 has been precoated onto 96-well plates. Standards(CHO, E26-G586) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CD105 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human CD105 amount of sample captured in plate.

Additional Information: The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: CD105, also called Endoglin, is a homodimeric membrane glycoprotein primarily associated with human vascular endothelium. It is also found on bone marrow proerythroblasts, activated monocytes, and lymphoblasts in childhood leukemia. Endoglin is a component of the transforming growth factor-beta(TGFB) receptor complex and binds TGFB1 with high affinity.1 CD105 gene is mapped to 9q34.1. The coding region of the gene contains 14 exons.2 The protein consists of a homodimer of 180 kDA with disulfide links. Endoglin has a role in the development of the cardiovascular system and in vascular remodeling. Its expression is regulated during heart development. Furthermore, it also has a role in the balance of ALK1 and ALK5 signaling to regulate endothelial cell proliferation.3 Moreover, the elevated expression of endoglin in the surgically excised CNVMs suggested a persisting postmitotic activation in an advanced stage of neovascular tissue.4 The standard product used in this kit is extracellular part of recombinant human CD105, from E26 to G586. As a result of glycosylation, the molecular mass is 75-85KDa.; Immunogen sequence: 400
