  • Anti-Cannabinoid Receptor I antibody (ab23703) + Human cerebellum at 30 µg

    Predicted band size : 53 kDa
    Observed band size : 60 kDa (why is the actual band size different from the predicted?)

    Secondary antibody - anti-rabbit HRP (ab6721)

  • Immunoperoxidase staining of CA region of rat hippocampus with the Cannabinoid Receptor I antibody (ab23703, 4ug/ml). the majority of the protein is localized in the pre-synaptic axons, shown as brown particulaes. A few neurons also show cytoplasm staining.
  • ab23703 staining Cannabinoid Receptor I in rat brain tissue by Immunohistochemistry (Frozen sections). After fixation in 4% PFA in PBS (pH 7.4), brains were cryoprotected in 30% sucrose in PBS at +4°C, frozen, and thereafter kept at -80°C until used. For the immunostaining, brains were cryosectioned in 30 µm slices, collected in PBS (pH 7.4), and processed in a free-floating system. Slices were first incubated in the blocking solution (BS) containing 2% bovine serum albumin, 2% goat serum, and 0.1% Triton X-100 in PBS (pH 7.4) for 1 hour at room temperature, and thereafter with the primary antibody for 24–48 hours at +4°C in BS at a 1/1000 dilution. After washing in PBS, slices were incubated with the biotin-conjugated secondary antibody (1/4000) in BS, rinsed with PBS, and incubated with the avidin-peroxidase conjugate in BS for 1 hour at room temperature. The staining was detected using 3,3-diaminobenzidinetetrahydrochloride as a chromogen.
  • Immunofluorescence analysis of mouse cultured hippocampal neurons, staining Cannabinoid Receptor I with ab23703.

    Cells were fixed with paraformaldehyde, permeabilized with 0.05% Saponin and blocked with 10% fetal calf serum for 2 hous at 4°C. Samples were incubated with primary antibody (1/200 in 0.05% Saponin + fetal calf serum) for 12 hours at 23°C. An AlexaFluor®488-conjugated goat anti-rabbit polyclonal IgG (1/400) was used as the secondary antibody.

  • ab23703 staining Cannabinoid Receptor I in human pancreas tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 5% serum for 1 hour at room temperature; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/50 in PBS) for 8 hours at 4°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/1000) was used as the secondary antibody.
