Designing a Western blot for RAB13? 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 RAB13 Western Blot GuideFacts about Ras-related protein Rab-13.
That Rab is involved in endocytic recycling and modulates the transfer to the plasma membrane of transmembrane proteins such as the tight junction protein OCLN/occludin. Thereby, it modulates the assembly and the activity of tight junctions.
