Immunohistochemical analysis of formalin fixed paraffin embedded human pancreas labelling STAT3 with ab68153 at a concentration of 0.1μg/ml.

The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with an OptiView HRP/DAB detection kit.

Heat mediated antigen retrieval was performed with DISCOVERY cell conditioning solution (CC1) 100°C, pH8.5 for 32mins.

ab68153 anti-STAT3 antibody [EPR787Y] was incubated for 16mins at 37°C. Sections were counterstained with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.

Customers are encouraged to optimise antigen retrieval conditions, antibody concentration, incubation times and temperature for best results in their own IHC assay workflow (automated and manual).

Western blot - Anti-STAT3 antibody [EPR787Y] - BSA and Azide free (AB171359)

This data was developed using the same antibody clone in a different buffer formulation (ab68153).

Lanes 1- 2 : Merged signal (red and green). Green - ab68153 observed at 92 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

ab68153 was shown to react with STAT3 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab255436 (knockout cell lysate ab263797) was used. Wild-type HeLa and STAT3 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab68153 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

ChIC/CUT&RUN sequencing - Anti-STAT3 antibody [EPR787Y] - BSA and Azide free (AB171359)

This data was developed using the same antibody clone in a different buffer formulation (ab68153). ChIC/CUT&RUN was performed using a pAG-MNAse at a final concentration of 700 ng/mL, 2.5 x 10^5 HepG2 cells (starved overnight and treated with 100ng/ml IL-6 for 30min) and 5 µg of ab68153 [EPR787Y]. The resulting DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 10 million reads. The negative IgG control ab172730 is also shown. Additional screenshots of mapped reads can be found in the Protocol booklet in the Product Protocol section. The University of Geneva owns patents relevant to ChIC (Chromatin Immuno-Cleavage) methods.
