Anti-Rab5 antibody - Drosophila Early Endosome Marker images

  • ab31261 staining 3rd instar wing imaginal disc cells of fruit fly (Drosophila melanogaster).  Cells were formaldehyde fixed and blocked with 5 % serum for 2 hours at 22°C prior to incubating with the primary antibody, diluted 1/500, for 16 hours at 4°C.  A Cy3® conjugated donkey anti-rabbit IgG (H+L) antibody, diluted 1/500, was used as the secondary.

    In the image, the nuclei of some cells are marked by GFP (green).  The punctate, non-nuclear staining pattern is indicative of endosomes (similar to other endosomal markers such as Hrs).

    Performed under reducing conditions.

    Predicted band size : 26 kDa
    Observed band size : 26 kDa
    Additional bands at : 135 kDa,145 kDa. We are unsure as to the identity of these extra bands.

  • ab31261 staining Rab5 in Drosophila S2 cells by Immunocytochemistry/ Immunofluorescence.
    S2 cells were fixed in 4% paraformaldehyde for 10 minutes and then permeablized by incubating with 0.2% Triton X-100 in PBS for 5 minutes at room temperature. After blocking, cells were incubated overnight with ab31261 diluted in PBS containing 10% horse serum and 0.2% Triton X-100. A Fluorescein-conjugated anti-rabbit IgG was used as the secondary.
