Stemcell, 100-1321, Human Recombinant ANGPTL2

Use angiopoietin-like protein 2 (ANGPTL2) to regulate tissue remodeling through integrin α5β signaling and activation of p38 mitogen-activated protein kinases (MAPK) (Odagiri et al.; Tabata et al.). Highly expressed in the heart, small intestine, and stomach, ANGPTL2 is a glycosylated secretory protein that contains a coiled domain and a fibrinogen-like domain (Kim et al.). Studies have shown that the coiled-coil domain of ANGPTL2 functions as a growth factor, enhancing the survival of hematopoietic stem cells (HSCs) ex vivo (Broxmeyer et al.). ANGPTL2 is also known to play a role in obesity and metabolic diseases, promoting local inflammation in adipose tissue and systemic insulin resistance in mice models (Tabata et al.). By activating an inflammatory cascade in endothelial cells and increasing macrophage infiltration, ANGPTL2 accelerates vascular inflammation which may lead to endothelial dysfunction and atherosclerosis progression (Horio et al.). This protein product contains a His-residue tag at the amino end of the polypeptide chain. For consistency and reproducibility across your applications, sclerostin from STEMCELL comes lyophilized with ≥ 92% purity, and endotoxin levels are verified to be ≤ 1.0 EU/μg protein.
