This data was developed using ab254407, the same antibody clone in a different buffer formulation.

Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HaCaT cells labelling Smad2 (phospho T8) + Smad3 (phospho T8) with ab254407 at 1/50 (9.34 ug/ml) dilution, followed by ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) antibody at 1/1000 dilution (Green). Confocal image showing weak cytoplasmic and nuclear staining in HaCaT cells, while strong cytoplasmic and weak nuclear staining in HaCaT cells treated with calyculin A (100 nM) for 30 mins is observed. ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor^® 594) was used to counterstain tubulin at 1/200 dilution (Red). The Nuclear counterstain was DAPI (Blue).

Calyculin A is a known phosphatase inhibitor, which increased the level of pSmad2/3 (T8). The shifted band after treated with Calyculin A might be due to multiple phosphorylation events.

The down-regulation of pSmad2 (T8) is induced by TGF-beta1 treatment in HaCaT (PMID : 19201832).

Bands between 15-25kDa may be caused by degradation.

ChIC/CUT&RUN was performed using a pAG-MNAse at a final concentration of 700 ng/mL, 2 x 10^5 HaCaT (human skin keratinocyte) cells and 5µg of ab254407 [EPR23682-64]. 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. This data was developed using ab254407, the same antibody clone in a different buffer formulation.
