Product details:
Mouse Endostatin ELISA Kit (ab263894) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Endostatin protein in cell culture supernatant, cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse Endostatin with 2.33 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Endostatin is a cleaved product of the C-terminal domain of collagen XVIII, an endogenous angiogenesis inhibitor. Endostatin localized to wall of vasculature in the elastic fiber and basement membrane where it inhibits endothelial cell migration, in vivo and in vitro. Endostatin induces endothelial cell apoptosis and inhibits tumor growth and impairs blood vessel maturation in wound healing. It is implicated in endothelial cell adhesion and cytoskeletal organization. Mouse endostatin shares a 70, 67, 67% sequence homology with human, rat, and cow, respectively.

Endostatin also known as Collagen XVIII alpha 1 (COL18A1) is a powerful anti-angiogenic protein with a mass around 20 kDa. It specifically inhibits the process of blood vessel formation in both in vitro and in vivo environments. This protein derives as a fragment from the carboxyl end of collagen XVIII which is a component of basement membranes. Expression of endostatin occurs primarily in the endothelial cells lining blood vessels and is also seen in tissues undergoing remodeling or repair.
Biological function summary
Endostatin functions as an important inhibitor of angiogenesis the process in which new blood vessels form from pre-existing ones. It acts independently and is not part of a larger protein complex. In the cellular microenvironment endostatin binds to various integrins inhibiting endothelial cell proliferation and inducing apoptosis. It also disrupts signal transduction pathways critical for endothelial cell survival and migration.
Pathways
Endostatin holds an important position in the angiogenesis and Wnt signaling pathways. It interacts closely with proteins like VEGF (Vascular Endothelial Growth Factor) and FGF2 (Fibroblast Growth Factor 2) where it counteracts their pro-angiogenic effects. Endostatin's role in these pathways indicates its significant impact on controlling angiogenic balance in various physiological and pathological conditions.
Endostatin exhibits notable relevance to cancer and diabetic retinopathy. In cancer the protein suppresses tumor-induced angiogenesis restricting tumor growth and metastasis. Likewise in diabetic retinopathy endostatin's inhibition of abnormal blood vessel formation in the retina offers potential therapeutic benefits. In these contexts it interacts with other key proteins like MMPs (matrix metalloproteinases) which regulate collagen degradation and release of endostatin fragments from parent collagen XVIII.
