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. SNF2H antibody produces CUT&RUN peaks above background (Figure 1) that overlap with H3K4me3 (Figures 1-2), consistent with its known role as the ATP-dependent helicase subunit of the ISWI chromatin remodeler complex [1].

Validation Data

Figure 1: SNF2H enrichment at annotated transcription start sites (TSSs) in CUT&RUN
CUT&RUN was performed using 500,000 K562 cells with SNF2H (0.1 µg) and control antibodies (0.5 µg; IgG negative control, EpiCypher 13-0042; H3K4me3 positive control, EpiCypher 13-0041). Sequencing reads were aligned to annotated TSSs (+/- 2 kbp) of 18,793 genes. High, medium, and low signal is ranked by intensity (top to bottom) and reflected by red, yellow, and blue colors, respectively. Rows aligned relative to SNF2H antibody.

Figure 2: SNF2H CUT&RUN peaks and functional overlap
Two representative gene loci from the CUT&RUN data in Figure 1 are shown. SNF2H enrichment overlaps with H3K4me3 CUT&RUN peaks (EpiCypher 13-0041), consistent with the reported function of SNF2H as a subunit of ISWI chromatin remodeler complex (1). Images were generated using the Integrative Genomics Viewer (Broad Institute).

Figure 3: Western blot detection of human SNF2H
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 SNF2H antibody (0.04 µg/mL).

Figure 4: Immunoprecipitation of human SNF2H
EpiCypher SNF2H antibody (3 µg) was used to immunoprecipitate whole cell lysates isolated from HeLa cells using NETN lysis buffer (1.0 mg per IP). A negative control IgG antibody and positive control antibody to different SNF2H 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 SNF2H antibody (1.0 µg/mL).
