Immunofluorescence staining of GFAP using ab207165 in primary rat hippocampal mixed glia, (prepared from P2 rat hippocampal brain area, obtained from Transnetyx Tissue by BrainBits, LLC, cat.no. SDPHP4m), DIV4. The cells were fixed with 100% MeOH (5 min), permeabilized with 0.1% Triton-X-100 (in PBS) for 5 mins and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab207165 at 0.1 μg/ml and Anti-GFAP antibody - Astrocyte Marker ab4674, Anti-GFAP antibody, at 1/1000 dilution. Cells were then incubated with Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed ab150081, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed at 1/1000 dilution (shown in green) and Goat Anti-Chicken IgY H&L (Alexa Fluor® 594) preadsorbed ab150176, Goat Anti-Chicken IgY H&L (Alexa Fluor® 594) preadsorbed at 1/1000 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).
Images were acquired with the Perkin Elmer Operetta HCA and a maximum intensity projection of confocal sections is shown. The antibody ab207165 gave comparable results using 4% formaldehyde fixation (10 min).
