Recombinant Mouse Activin Receptor-like Kinase 1 Protein

Supplier: Elabscience Product Name: Recombinant Mouse Activin Receptor-like Kinase 1 Protein Catalog No. PKSM041235 Product Type: recombinant protein Size: 50 ug Activity: Measured by its ability to inhibit BMP9-induced alkaline phosphatase production by MC3T3E1 mouse chondrogenic cells. David, L. et al. (2007) Blood 109:1953.The ED50 for this effect is typically 60-300 ng/mL in the presence of 2 ng/mL of recombiant human BMP9. Protein Construction: Recombinant Mouse Activin Receptor-like Kinase 1 is produced by our Mammalian expression system and the target gene encoding Asp23-Pro119 is expressed with a Fc tag at the C-terminus. Sequence: Asp23-Pro119 Fusion Tag: C-Fc Accession: Q61288 Species: Mouse Expressed Host: Human Cells Shipping Conditions: In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Purity: ?95% as determined by reducing SDS-PAGE. Endotoxin: <1.0 EU per ?g as determined by LAL test. Stability: Lyophilized protein should be stored at < -20?, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7? for 2-7 days.Aliquots of reconstituted samples are stable at < -20? for 3 months Molecular Weight: 38.1 kDa Applied MM: 55-60 kDa Formulation: Lyophilized from a 0.2 ?m filtered solution of PBS, pH 7.4. Reconstitution: Please refer to it for detailed information. Background: Activin Receptor-Like Kinase 1 (ALK-1) is a type I cell-surface receptor for the TGF-? superfamily of ligands, which mediates signaling of BMP9 (bone morphogenetic protein) and BMP10. ALK1 signaling is necessary for angiogenesis during embryogenesis, wound healing, and tumor growth. ALK-1 has a high degree of similarity in serine-threonine kinase subdomains, a glycine and serine rich region preceding the kinase-domain, and a C-terminal tail with other activin receptor-like kinase proteins. ALK-1 is mainly expressed in endothelial cells regulating proliferation and migration in vitro and angiogenesis in vivo. Mutations in ALK-1 as well as in endoglin are associated with hereditary hemorrhagic telangiectasia (HHT), suggesting ALK-1 plays a critical role for in the control of blood vessel development or repair.
