Activin receptor-like kinase (ALK) 7 is a type I serine/threonine kinase receptor of the transforming growth factor (TGF)-beta family of proteins.1 ALK7 is most abundantly expressed in human brain, pancreas and colon.2 It negatively regulates glucose-stimulated insulin release in β-cells3 and plays an important role in regulating the functional plasticity of pancreatic islets.3 ALK7 also has an important role in the regulation of body fat deposition. These has implications for the development of treatments against diabetes and obesity.3

N-terminal Sequence Analysis
State of Matter
Predicted Molecular Mass
The predicted molecular weight of Recombinant Rat ALK-7 is Mr 35.7 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 47-55 kDa.
This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
Storage and Stability
This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
