Species: Human Expressing host: HEK293 cells Description: Recombinant Human ALK-1 Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Asp22-Gln118) of human ALK-1 (Accession #NP_000011.2) fused with a 6His tag at the C-terminus. Tag: C-His Purity: > 95% by SDS-PAGE. Endotoxin: Please contact us for more information. Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized Human ALK-1 at 4 g/mL (100 L/well) can bind Human ACVR2B with a linear range of 0.08-2.4 g/mL. preparation: Lyophilized from a 0.22 m filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. Storage Store the lyophilized protein at -20C to -80 C for long term.
After reconstitution, the protein solution is stable at -20 C for 3 months, at 2-8 C for up to 1 week.Unopened freeze-dried powder,Store at -20 to -80 °C for twelve months
Redissolution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.Redissolution:Store at -20 to -80 °C,avoid repeated freeze thaw cycles
Background Information : This protein is a type I cell-surface receptor for the TGF-beta superfamily of ligands. It shares with other type I receptors a high degree of similarity in serine-threonine kinase subdomains, a glycine- and serine-rich region (called the GS domain) preceding the kinase domain, and a short C-terminal tail. The protein, sometimes termed ALK1, shares similar domain structures with other closely related ALK or activin receptor-like kinase proteins that form a subfamily of receptor serine/threonine kinases. GeneID 94 Swiss Prot P37023 Alias: ACVRL1;ACVRLK1;ALK-1;ALK1;HHT;HHT2;ORW2;SKR3;TSR-I; ALK-1; ALK1; HHT; HHT2; ORW2; SKR3; TSR-IMedChemExpress (MCE) recombinant proteins include: cytokines, enzymes, growth factors, hormones, receptors, transcription factors, antibody fragments, etc. They are often essential for supporting cell growth, stimulating cell signaling pathways, triggering or inhibiting cell differentiation; and are useful tools for elucidating protein structure and function, understanding disease onset and progression, and validating pharmaceutical targets. At MedChemExpress (MCE), we strive to provide products with only the highest quality. Protein identity, purity and biological activity are assured by our robust quality control and assurance procedures.
