Immunocytochemistry/ Immunofluorescence - Anti-Ras antibody [EP1125Y] - BSA and Azide free (AB271848)

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab52939).

ab52939 staining of GTPase KRas in a HCT 116 cell spheroid. The cells were fixed with 4% paraformaldehyde (10 min), permeabilised with 2% Triton X-100 for 1h and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween overnight at room temperature. The spheroids were then incubated overnight at room temperature with ab52939 at 2 μg/ml and ab7291, Mouse monoclonal [DM1A] to alpha Tubulin at 2 μg/ml. DAPI was used as nuclear counterstain (shown in blue). As secondary antibodies ab150081 Goat anti-Rabbit (Alexa Fluor^® 488) (shown in green) and ab150120 Goat anti-Mouse (Alexa Fluor^® 594) (shown in magenta) were used, incubated overnight at room temperature. All permeabilization, blocking and antibody incubation steps were performed using a rotary shaker.

Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.

Similar results were observed using 100% Methanol (5min).

Immunocytochemistry/ Immunofluorescence - Anti-Ras antibody [EP1125Y] - BSA and Azide free (AB271848)

Immunocytochemistry analysis of MCF7 (human breast adenocarcinoma cell line) cells labeling Ras with Purified ab52939 at 1 : 500 dilution. Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor ® 594) 1 : 200 (2.5 μg/ml). ab150077 Goat anti rabbit IgG(Alexa Fluor ® 488) was used as the secondary antibody at 1 : 1000 dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab52939).
