Arf6 Pull-Down Activation Assay Kit

Cat. # TD-82401

Background

ARF6 (ADP-ribosylation factor 6) is a member of the ARF super-family. ARF genes encode small GTPases that increase the ADP-ribosyltransferase activity of cholera toxin and are critical for vesicular trafficking as activators of phospholipase D. Arf6 regulates membrane trafficking and functions as a regulatory molecule of phagocytosis.

Currently there is no direct assay to measure the activation of Arf6 GTPase.

Assay Principle

The Arf6 Activation Assay Kit uses configuration-specific anti-Arf6-GTP Mouse monoclonal antibody to measure Arf6-GTP levels in cell extracts or in vitro GTPγS loading Arf6 activation assays. Anti-Arf6-GTP mouse monoclonal antibody is first incubated with cell lysates containing Arf6-GTP. Next, the GTP-bound Arf6 is pulled down by protein A/G agarose. Finally, the precipitated Arf6-GTP is detected through immunoblot analysis using Anti-Arf6 Rabbit Polyclonal Antibody.

The anti-Arf6-GTP monoclonal antibody can also be used to monitor the activation of Arf6 in cells and in tissues by immunohistochemistry.
