The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 46 kDa (predicted molecular weight: 58 kDa).
Use a concentration of 5 µg/ml.
A Rab11 effector binding preferentially phosphatidylinositol 3,4,5-trisphosphate (PtdInsP3) and phosphatidic acid (PA) and acting in the regulation of the transport of vesicles from the endosomal recycling compartment (ERC) to the plasma membrane. Involved in insulin granule exocytosis. Also involved in receptor-mediated endocytosis and membrane trafficking of recycling endosomes, probably originating from clathrin-coated vesicles. Required in a complex with MYO5B and RAB11 for the transport of NPC1L1 to the plasma membrane. Also acts as a regulator of cell polarity.
Contains 1 C2 domain. Contains 1 FIP-RBD domain.
Phosphorylation at Ser-227 by MARK2 regulates epithelial cell polarity.
Cell membrane. Recycling endosome membrane. Translocates with RAB11A from the vesicles of the endocytic recycling compartment (ERC) to the plasma membrane.
The predicted molecular weight of RAB11-FIP2 is 58 kDa (Swissprot), but we are unsure of the reason why a reaction at 46 kDa is observed. Further characterization on this product is underway. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
ICC/IF image of ab76892 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab76892, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
