Estrogen Receptor Alpha (C-Terminal) CUTANA™ CUT&RUN Antibody
11 in stock
Powered by BiozThis antibody meets EpiCypher’s “CUTANA Compatible” criteria for performance in Cleavage Under Targets and Release Using Nuclease (CUT&RUN) and/or Cleavage Under Targets and Tagmentation (CUT&Tag) approaches to genomic mapping. Every lot of a CUTANA Compatible antibody is tested in the indicated approach using EpiCypher optimized protocols and determined to yield peaks that show a genomic distribution pattern consistent with reported function(s) of the target protein. Estrogen Receptor Alpha C-terminal (ER alpha C-term) antibody shows CUT&RUN peaks in response to estradiol stimulation (Figure 1) that overlap with known estrogen response element (ERE) binding motifs (Figure 2). Overlap is further observed with peaks from an antibody to a different ER alpha epitope (N-term) and NCOA3 (SRC3), which co-activates ER-mediated transcription [1] (Figure 2).

Serum-starved MCF7 cells were treated with estradiol (E2) or vehicle control for 45 minutes. CUT&RUN was performed on 500k cells with 0.5 µg of either ER Alpha (C-Term), ER Alpha (N-Term; EpiCypher 13-2011), NOCA3/SRC3 (EpiCypher 13-2013), H3K4me3 positive control (EpiCypher 13-0041), or IgG negative control (EpiCypher 13-0042) antibodies using the CUTANA™ ChIC/CUT&RUN Kit v2.0 (EpiCypher 14-1048). Library preparation was performed with 5 ng of DNA (or the total amount recovered if less than 5 ng) using the CUTANA™ CUT&RUN Library Prep Kit (EpiCypher 14-1001/14-1002). Both kit protocols were adapted for high throughput Tecan liquid handling. Libraries were run on an Illumina NextSeq2000 with paired-end sequencing (2×50 bp). Data were aligned to the hg19 genome using Bowtie2. Data were filtered to remove duplicates, multi-aligned reads, and ENCODE DAC Exclusion List regions.
