Activin A Receptor, Type Ib (ACVR1B), recombinant human protein is supplied as a lyophilized powder. In general, recombinant proteins are suitable for use in studying protein-protein interactions, as a protein standard, or in cell biology research applications.

Since this product is a truncated protein and does not contain intracellular catalytic activity domain, it is not suitable for use in enzyme activity studies.

This recombinant protein was expressed from a DNA sequence encoding the human ACVR1B (NP_004293.1) extracellular domain (Met 1-Glu 126) fused to C-terminal His-tagged Fc region of human IgG1 at the C-terminus.

Activity: Measured by its binding ability in a functional ELISA. Immobilized human TDGF1 at 2 µg/ml (100 µl/well) can bind human ACVR1B with a linear range of 0.0068-0.16 µg/ml.

Formulation: 140 mM NaCl, 2.7 mM KCl, 10 mM Na2HPO4, 1.8 mM KH2PO4, pH7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.

This protein is manufactured by Sino Biological Inc.

For Research Use Only. Not for use in diagnostic procedures.
