            | Description | 
            Recombinant Human Activin Receptor-Like Kinase 1/ALK-1 is produced with our mammalian expression system in human cells. The target protein is expressed with sequence (Asp22-Gln118) of Human ACVRL1 fused with a polyhistidine tag at the C-terminus. |

            | Formulation | 
            Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2 | 
        
        
            | Shipping | 
            The product is shipped at ambient temperature. | 
        
        
            | Reconstitution | 
            Always centrifuge tubes before opening. Do not mix by vortex or pipetting. 
            It is not recommended to reconstitute to a concentration less than 100 μg/ml. 
            Dissolve the lyophilized protein in 1X PBS. 
            Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | 
        
        
            | Storage | 
            Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 
            Reconstituted protein solution can be stored at 4-7°C for 2-7 days. 
            Aliquots of reconstituted samples are stable at < -20°C for 3 months. | 
        
        
            | Purity | 
            Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. | 
        
        
            | Endotoxin | 
            Less than 0.1 ng/μg (1 IEU/μg). |

            | Background | 
            Activin Receptor-Like Kinase 1 (ALK-1) is a type I cell-surface receptor for the TGF-βsuperfamily of ligands. 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. The mutations of ALK-1 are associated with Rendu-Osler-Weber syndrome 2, this suggests ACVRL1 is associated with blood vessel development and repair |
