W19419E_PURE_-Angiopoietin-2_Direct-ELISA_100424
Direct ELISA showing purified anti-human Angiopoietin-2 (clone W19419E) bound to plate-immobilized recombinant human Angiopoietin-2 (Cat. Nos. 753102, 753104, and 753106). The wells were incubated with serially diluted primary antibody at room temperature for 2 hours in 1% BSA-PBS, followed by incubation with HRP Goat anti-rat IgG (Cat. No. 405405). TMB High Sensitivity Substrate Solution (Cat. No. 421501) was used for detection. Absorbance was measured at 450 nm.

Description

Angiopoietin-2, also known as ANGPT2, is a member of angiopoietins, which plays essential roles in embryonic and postnatal angiogenesis. The structure of the mature form of ANGPT2 contains an N-terminal coiled-coil domain, which mediates multimerization of the protein, along with a C-terminal fibrinogen-like domain, which mediates the receptor binding. Both ANGPT1 and ANGPT2 are ligands for the receptor tyrosine kinase, Tie-2. ANGPT2 appears to exist predominantly as a homodimer, but it is also capable of forming multimers while ANGPT1 predominantly exists as multimers. It has been shown that ANGPT2 is able to promote vascular leakage and neutrophil migration. ANGPT2 can also sensitize TNF-α-induced monocyte adhesion, thus it is considered a proinflammatory factor. Although ANGPT2 is not required for arterial vascular development, its expression in the tissue suggests that it may play a role in the maintenance of these vessels. This conclusion is also supported by the observation that high concentrations of ANGPT2 activate the same survival signaling pathway as ANGPT1 to prevent endothelial cell apoptosis via Tie-2/Akt. Additionally, ANGPT2 was demonstrated to function as an agonist in the absence of ANGPT1, but in its presence, it acts as an antagonist. Human ANGPT2 shares 86% amino acid sequence homology with its murine counterpart.

Additional Product Notes

This product is intended for sandwich-based immunoassay development on various assay platforms requiring antibody pairs. This antibody (clone W19419E) could function as a capture antibody when paired with biotin anti-human Angiopoietin-2 (Cat No. 629453) (clone A15124B) as the detection antibody and using Recombinant Human Angiopoietin-2 (carrier-free) (Cat. Nos. 753102, 753104, and 753106) protein as the assay standard.
