Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-TROP2 antibody [162-46.2] - BSA and Azide free (AB238669)

ab79976 staining TROP2 in human 10 week placenta by Immunohistochemistry, Formalin-fixed, Paraffin-embedded tissue. Anti-mouse peroxidase IgG used as secondary antibody. Note staining of cytotrophoblast (CT) and syncytiotrophoblast (ST).

This data was developed using the same antibody clone clone in a different formulation containing PBS, Azide and arginine (ab79976).

Overlay histogram showing MCF7 cells stained with ab79976 (red line). The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab79976, 1μg/1x10⁶ cells) for 30 min at 22°C. The secondary antibody used was DyLight^® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2μg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive result in 4% paraformaldehyde (10 min) fixed MCF7 cells used under the same conditions.

Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

Immunocytochemistry/ Immunofluorescence - Anti-TROP2 antibody [162-46.2] - BSA and Azide free (AB238669)

This data was developed using the same antibody clone in a different buffer formulation without PBS and sodium azide (ab79976)

ab79976 staining TROP2 in MCF7 cells. The cells were fixed with 4% paraformaldehyde (10 min), permeabilized with 0.1% PBS-Tween for 5 minutes 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 ab79976 at 1µg/ml and ab6046, Rabbit polyclonal to beta Tubulin - Loading Control. Cells were then incubated with ab150117, Goat polyclonal Secondary Antibody to Mouse IgG H&L (Alexa Fluor^® 488) preadsorbed at 1/1000 dilution (shown in green) and ab150080, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor^® 594) at 1/1000 dilution (shown in pseudocolour red). Nuclear DNA was labelled with DAPI (shown in blue).

Image was acquired with a confocal microscope (Leica-Microsystems TCS SP8) and a single confocal section is shown.

Flow Cytometry (Intracellular) - Anti-TROP2 antibody [162-46.2] - BSA and Azide free (AB238669)

Overlay histogram showing JEG3 cells stained with ab79976 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab79976, 0.1μg/1x10⁶ cells) for 30 min at 22°C. The secondary antibody used was Alexa Fluor^® 488 goat anti-mouse IgG (H&L) (ab150117) at 1/2000 dilution for 30 min at 22°C.

Isotype control antibody (black line) was mouse IgG1 [15-6E10A7] (monoclonal) (ab170190) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter.

This antibody gave a positive signal in JEG3 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Triton X-100 for 15 min used under the same conditions.

This data was developed using the same antibody clone clone in a different formulation containing PBS, Azide and arginine (ab79976).
