We Western blot - Rab5 antibody (ab18211) are unsure as to the identity of these extra bands. 2 ICC/IF image of ab18211 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab18211, 1µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBST) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Immunocytochemistry/ Immunofluorescence - Fluor® 594 WGA was used to label plasma Rab5 antibody - Early Endosome Marker membranes (red).

Predicted band size : 24 kDa Observed band size : 25 kDa 3 ab18211 at 1/300 staining adult rat brain (perfusion fixed) tissue sections by IHC-Fr. Adult rat was perfused intracardially with paraformaldehyde 4% in PB 0.2M. The brain was post-fixed in the same fixative for 24 hours. Sections were cryoprotected with sucrose 20% and later frozen in OCT. Sections were incubated in free floating for 12h with the primary antibody (1/300) and Immunohistochemistry (Frozen sections) - Rab5 later revealed with secondary antibody antibody - Early Endosome Marker (ab18211) conjugated with Alexa Fluor ® 488 (1/2000). This image is courtesy of an Abreview submitted by Dr Sophie Pezet The staining obtained is restricted to the cytoplasm and consists of a small and thin punctate staining. The picture shows the staining obtained at the level of the spinal cord using the X20 objective and zooming on two particular neurons. ab18211 immunoprecipitated Rab5 in Mouse neuroblastoma N2a whole cell lysate. 10µg of cell lysate was incubaed with primary antibody (1/2000 in dilution buffer:0.025 M Tris, 0.15 M NaCl, 0.001 M EDTA, 1% NP40, 5% glycerol pH 7.4) for 2 hours at 22°C and an AminoLink® Plus Coupling Resin Immunoprecipitation - Rab5 antibody - Early matrix.
