This 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 CUTANA 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. BRM antibody produces CUT&RUN peaks above background (Figure 1) localized to gene transcription start sites (Figures 1-2), cconsistent with its known role as the ATP-dependent helicase subunit of the SWI/SNF chromatin remodeler complex (1).

Validation Data

Figure 1: BRM enrichment at annotated transcription start sites (TSSs) in CUT&RUN
CUT&RUN was performed using 500,000 K562 cells with BRM (0.1 µg) and control antibodies (0.5 µg; IgG, EpiCypher 13-0042; H3K4me3, EpiCypher 13-0041). Sequencing reads were aligned to TSSs (+/- 2 kbp) of 18,793 genes. Signal (red) over background (blue) is ranked by intensity (top to bottom). All rows aligned to BRM antibody with moderate fixation (0.1% formaldehyde, 1 min), which improved signal vs. native conditions.

Figure 2: BRM CUT&RUN peaks and functional overlap
Two representative gene loci from the CUT&RUN data in Figure 1 are shown. BRM enrichment overlaps with H3K4me3 peaks, consistent with the reported function of BRM as a member of the SWI/SNF chromatin remodeler complex (1). Improved signal recovery with moderate fixation (0.1% formaldehyde, 1 min), is notable. Images generated in Integrative Genomics Viewer (Broad Institute).

Figure 3: Western blot detection of human BRM
Whole cell lysates were isolated from HeLa cells using NETN lysis buffer. The indicated amounts (µg) of lysate were loaded onto 4-8% SDS-PAGE gel and analyzed under standard western blot conditions using BRM antibody (0.04 µg/mL).

Figure 4: Immunoprecipitation of human BRM
EpiCypher BRM antibody (3 µg) was used to immunoprecipitate whole cell lysates isolated from HeLa cells using NETN lysis buffer (1 mg per IP). A negative control IgG antibody and positive control antibodies to various BRM epitopes (Bethyl Laboratories) were also used to demonstrate specificity of the IP. Immunoprecipitates were loaded onto 4-8% SDS-PAGE gel (20% of IP loaded) and probed via western blot with EpiCypher BRM antibody (1.0 µg/mL).
