ChIP analysis using unpurified ab32063 binding Estrogen Receptor alpha in MCF7 cells derived from Human breast carcinoma. Cells were cross-linked for 10 minutes with 1% formaldehyde. Samples were incubated with undiluted primary antibody for 16 hours at 4°C. Protein binding was detected using real-time PCR.
Positive control : Estrogen treated MCF7 cells tested at PS2 promoter.
Negative Control : IgG ChIP and ethanol-depleted cells tested at PS2 promoter.

ChIP - Anti-Estrogen Receptor alpha antibody [E115] - BSA and Azide free (AB271827)

Chromatin was prepared from MCF-7+β-estraiol 30 min, and MCF-7 cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 min. The ChIP was performed with 25 μg of chromatin, 4 μg of purified ab32063 (blue), and 20 μLl of anti-rabbit IgG sepharose beads. Rabbit normal IgG was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (SYBR approach). Primers are located in the 2nd intron of TFF1 gene.

MCF7 Cells were treated as below :

MCF-7 starved overnight, then treated with 10 nM β-Estradiol in 2% FBS media for 30 min.

Control MCF-7 was starved overnight, then in 2% FBS media for 30 mins.

Primer information :
