100ug (NPP1055) Please inquiry

Catalog Number	P10066-H08H
Organism Species	Human
Host	Human Cells
Synonyms	ACVRLK1,ALK-1,ALK1,HHT,HHT2,ORW2,SKR3,TSR-I
Molecular Weight	The recombinant human ALK1 comprises 108 amino acids and has a predicted molecular mass of 12.3 kDa. As a result of glycosylation, rhALK1 migrates as an approximately 27 kDa protein in SDS-PAGE under reducing conditions.
predicted N	Asp 22
SDS-PAGE
Purity	> 92 % as determined by SDS-PAGE
Protein Construction	A DNA sequence encoding the the extracellular domain of human ALK1 (NP_000011.2) (Met 1-Gln 118) was fused with a polyhistide tag at the C-terminus.
Bio-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 50-200 ng/mL in the presence of 2 ng/mL of recombiant human BMP9.
Research Area	Cancer \|Invasion microenvironment \|Angiogenesis \|Adhesion Molecules in Angiogenesis \|Extracellular Matrix \|Structures \|
Formulation	Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background	Activin A receptor, type II-like 1 (ACVRL1), also known as ALK-1 (activin receptor-like kinase 1), is an endothelial-specific type I receptor of the TGF-beta (transforming growth factor beta) receptor family of ligands. On ligand binding, a heteromeric receptor complex forms consisting of two type II and two type I transmembrane serine/threonine kinases. ACVRL1 protein is expressed in certain blood vessels of kidney, spleen, heart and intestine, serving as an important role during vascular development. Mutations in ACVRL1 gene are associated with hemorrhagic telangiectasia type 2, also known as Rendu-Osler-Weber syndrome 2 and vascular disease.
