Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Ras antibody [EPR23474-20] (ab275875)

Immunohistochemical analysis of paraffin-embedded Human colon tissue labeling Ras with ab275875 at 1/2000 (0.338 ug/ml) dilution followed by a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining on human colon. The section was incubated with ab275875 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. Counterstained with Hematoxylin.

Secondary antibody only control: Secondary antibody is a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.
Immunoprecipitation - Anti-Ras antibody [EPR23474-20] (ab275875)

Ras was immunoprecipitated from 0.35 mg HeLa (human cervix adenocarcinoma epithelial cell) whole cell lysate with ab275875 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab275875 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP)(ab131366) was used at 1/5000 dilution.

Lane 1: HeLa (human cervix adenocarcinoma epithelial cell) whole cell lysate 10 ug

Lane 2: ab275875 IP in HeLa whole cell lysate

Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab275875 in HeLa whole cell lysate

Blocking and dilution buffer and concentration: 5% NFDM/TBST.

Exposure time: 110 seconds.
Flow Cytometry - Anti-Ras antibody [EPR23474-20] (ab275875)

Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol-permeabilized HeLa (human cervix adenocarcinoma epithelial cell) cells labelling Ras with ab275875 at 1/50 dilution (1ug)(Red) compared with a Rabbit monoclonal IgG (ab172730) isotype control (Black) and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue).

A Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.
