Designing a Western blot for Activin receptor type-1B? The guide has the expected band size, antibodies backed by real blot images, the controls to run alongside, and protocols taken from published papers.
Open the ACVR1B Western Blot GuideFacts about Activin receptor type-1B.
Within the receptor complex, type-2 receptors (ACVR2A and/or ACVR2B) act as a main activin receptors whereas the type-1 receptors like ACVR1B act as downstream transducers of activin signals. Activin binds to type-2 receptor at the plasma membrane and triggers its serine- threonine kinase.
