Immunocytochemistry/ Immunofluorescence - Anti-Egr1 antibody [EPR15916] - BSA and Azide free (AB232448)

Confocal image showing nuclear and weakly cytoplasmic staining on Hela cells.

Immunocytometry/Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HeLa (human cervix adenocarcinoma ) cells labeling Egr1 with ab194357 at 1/200 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution. The cells were co-stained with ab7291, a mouse anti-tubulin antibody (1/1000) using ab150120, an Alexa Fluor^® 594-conjugated goat anti-mouse IgG (1/1000) as the secondary. Nuclei counterstained with DAPI (blue).

For negative control 1, ab194357 (1 : 200) was used, followed by (ab150120) anti-mouse secondary antibody at 1/1000 dilution. For negative control 2, (ab7291) mouse primary antibody (1/1000) was used followed by (ab150077) anti-rabbit secondary antibody 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 (ab194357).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Egr1 antibody [EPR15916] - BSA and Azide free (AB232448)

Immunohistochemical analysis of paraffin-embedded human thyroid carcinoma tissue labeling Egr1 with ab194357 at 1/250 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Counter stained with hematoxylin.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab194357).

Heat mediated antigen retrieval was performed with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

Western blot - Anti-Egr1 antibody [EPR15916] - BSA and Azide free (AB232448)

This data was developed using the same antibody clone in a different buffer formulation  (ab194357). False colour image of Western blot : Anti-Egr1 antibody [EPR15916] staining at 1/10000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab194357 was shown to bind specifically to Egr1. A band was observed at 73 kDa in wild-type HeLa cell lysates with no signal observed at this size in EGR1 CRISPR-Cas9 edited cell line ab274929 (CRISPR-Cas9 edited cell lysate ab274987). The band observed in the CRISPR-Cas9 edited lysate lane below 73 kDa is likely to represent a truncated form of Egr1. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and EGR1 CRISPR-Cas9 edited HeLa cell lysates were analysed. 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.
