ChIP (chromatin immunoprecipitation) tips and tricks

WebPCR products were observed for each primer set in the input sample (lane 1) and various ChIP samples, but not in the Normal Rabbit IgG ChIP sample (lane 5). Show Less Show More. FIGURE 3. Chromatin immunoprecipitations were performed using digested chromatin from HeLa cells and the indicated ChIP-validated antibodies. WebCells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 2µg of ab177178 (blue), and 20µl of Anti rabbit IgG sepharose beads. 2μg of rabbit normal IgG was added to the beads as a control sample (yellow). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach). margaret castillo bynoe
