Description
The Human ALK-7 (Activin E receptor) (Luc) HEK293 Reporter Cell was engineered to not only express Smad signaling response element, but also express the receptor full length human ALK-7 (Uniprot: Q8NER5-1). When stimulated with human Activin E protein, receptor-mediated signaling can drive Smad-mediated luminescence. Inhibition of biological effect of human Activin E protein by corresponding inhibitors results in a decrease in luminescence.
Application
• Screen for neutralizing antibodies blocking the ligand-receptor interaction
• Screen for human ALK-7 small molecule inhibitor

Receptor Assay

Expression analysis of human ALK-7 on Human ALK-7 (Activin E receptor) (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human ALK-7 (Activin E receptor) (Luc) HEK293 Reporter Cell or negative control cell using anti-human ALK-7 antibody followed by staining with APC anti-human IgG Fc Antibody.Protocol
Application

Inhibition of human Activin E protein-induced reporter activity by anti-human ALK-7 neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human Activin E protein with a final concentration of 0.003 μg/mL. The EC50 of anti-human ALK-7 neutralizing antibody is approximately 0.2304 μg/mL.Protocol
Inhibition of human Activin E protein-induced reporter activity by human ALK-7 small molecule inhibitor.
This reporter cell was incubated with serial dilutions of inhibitors in the presence of human Activin E protein with a final concentration of 0.003 μg/mL. The EC50 of human ALK-7 small molecule inhibitor was approximately 0.01536 μM.Protocol
Signaling Bioassay

Response to human Activin E protein (RLU).
The Human ALK-7 (Activin E receptor) (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human Activin E protein. The EC50 was approximately 0.002345 μg/mL.Protocol
Response to human Activin E protein (FOLD).
The Human ALK-7 (Activin E receptor) (Luc) HEK293 Reporter Cell stimulated with serial dilutions of human Activin E protein. The max induction fold was approximately 826.97.Protocol
