Immunocytochemistry/ Immunofluorescence - Anti-RFP antibody [EPR18992] - BSA and Azide free (AB240297)

Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized Empty vector transfected or RFP transfected HEK-293 (Human epithelial cell line from embryonic kidney) cells labeling RFP with ab185921 at 1/100 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green).

Confocal image showing positive staining after transfection of RFP on HEK-293 cells.

The nuclear counterstain is DAPI (blue).

Tubulin is detected with Anti-alpha Tubulin antibody [EPR18992] - Loading Control (ab7291) at 1/1000 dilution and Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed (ab150120) at 1/1000 dilution (red).

The negative controls are as follows : -

-ve control 1 : ab185921 at 1/100 dilution followed by ab150120 at 1/1000 dilution.

-ve control 2 : ab7291  at 1/1000 dilution followed by ab150077  at 1/1000 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab185921).

Western blot - Anti-RFP antibody [EPR18992] - BSA and Azide free (AB240297)

This data was developed using the same antibody clone in a different buffer formulation (ab185921).

Western blot : Anti-RFP antibody [EPR18992] (ab185921) staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab185921 was shown to bind specifically to RFP. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.
