Immunofluorescent analysis of RAB9 using RAB9 Monoclonal Antibody (Mab9) (Product# MA3-067 ) shows staining in A2058 Cells. RAB9 (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with an antibody recognizing RAB9 (Product# MA3-067 ) at a dilution of 1:100 over night at 4 °C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product# 35552 for GAR, Product# 35503 for GAM). Images were taken at 60X magnification.

MA3-067 recognizes prenylated and non-prenylated rab 9 from canine, human, monkey, rat, hamster and bovine tissues. This antibody does not cross-react with other rab family members.
MA3-067 has been successfully used in Western blot, immunofluorescence, EM immunocytochemistry and immunoprecipitation procedures. By Western blot, this antibody detects an ~26 kDa protein representing rab 9 from K562 cell extract.
The MA3-067 antigen is recombinant canine rab 9a.
Rab proteins are a family of Ras-like GTPases involved in intracellular compartment protein transport. Different members of the 40+ member rab family are responsible for docking and fusion of transport vesicles between different compartments within the cell. Rab 9 is required for trafficking mannose 6-phosphate receptor between the late endosome to trans-Golgi network (TGN). By facilitating receptor transport, rab 9 enables cells to efficiently recycle important cellular trafficking components.
It is functionally necessary for rab 9, like other rab family members, to be prenylated by two 20-carbon geranylgeranyl groups at the C-terminus. Most prenylated rab 9 is membrane bound, however, 10-20% of the cellular pool of rab 9 is bound to GDP dissociation inhibitor-alpha (GDI-alpha) in the cytosol. GDI recycles prenylated, GDP bound rab 9 from their fusion targets back to their membranes of origin.
