All lanes : Anti-Histone H3 (citrulline R26) antibody - ChIP Grade (ab19847) at 1/1000 dilutionLane 1 : MCF7 acid-extracted histonesLane 2 : MCF7 acid-extracted histones, treated with recombinant PADI2SecondaryAnti rabbit HRP conjugated at 1/10000 dilutiondeveloped using the ECL techniquePerformed under reducing conditions.
ab19847 gave a positive result in ELISA against the immunising peptide (ab20631) and a negative result using the non-modified equivalent peptide (ab2623). This indicates that ab19847 is specifically recognising Histone H3 citrulline R26.Green and Orange lines: ELISA against immunising peptide (ab20631)Red and Mauve lines: ELISA against non-modified peptide (ab2623)

ChIP of H3Cit26 at the TFF1 gene promoter of MCF-7 cells with ab19847. As expected H3Cit26 was enriched at the TFF1 promoter of cells treated with Estrogen for 45' (E) compared to cells treated with Ethanol as a negative control (U).
MCF-7 breast cancer cells were cultured for 3 days in DMEM phenol red-free medium supplemented with 10% charcoal-dextran-treated calf serum and treated with Estrogen for 45 min (positive control) or EtOH (negative control).The immunoprecipitated DNA was quantified by real time PCR (SYBR). Primers are located in ERE region (-273bp,-198bp relative to the TSS) of TFF1 gene.See Abreview
