  • Relevance

    The septins are a family of cytoskeletal GTPases that play an essential role in cytokinesis in mammalian cells. Septin 2 (Nedd5) is a mammalian septin known to associate with actin based structures such as the contractile ring and stress fibers. It is involved in cytokinesis and may assemble into a multicomponent structure.

Customer reviews and Q&As


Yes, we expect that ab179436 will recognize Xenopus laevis Septin 2, given that the amino acid sequence of the immunogen that generated the antibody is conserved 100% in the X. laevis protein. However, we have not tested and confirmed reactivity, so our guarantee does not apply to this species.
