R3, R-3, SETHKIR, MGC91691, Acvrl1

Catalog Number P10596-R03H
Organism Species Rat

Molecular Weight The secreted recombinant rat ACVRL1/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer comprises 343 amino acids with a predicted molecular mass of 38.7 kDa. As a result of glycosylation, it migrates as an approximately 50-55 kDa band in SDS-PAGE under reducing conditions.
predicted N Asp 17
SDS-PAGE
Purity > 90 % as determined by SDS-PAGE
Protein Construction A synthetic DNA sequence encoding the rat ACVRL1 (NP_071886.1) extracellular domain (Met 1-Ala 118) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 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 40-200 ng/mL in the presence of 2 ng/mL of recombiant human BMP9.

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.
