Description
This product provides a high throughput fluorescent readout of nucleosome remodeling when paired with enzymatically active remodeling complexes, such as SMARCA4, SMARCA2, and ACF (EpiCypher 15-1014, 15-1015, 15-1013). The EpiDyne®-FRET mononucleosome is assembled from recombinant human histones expressed in E. coli (two each of histones H2A-Cy5, H2B, H3.2 and H4; accession numbers: H2A-P04908; H2B-O60814; H3.2-Q71DI3; H4-P62805) wrapped with a 212 base-pair DNA template bearing a 5’ Cy3, the Widom 601 nucleosome positioning element [1], and a DpnII restriction enzyme motif (GATC) that is exposed upon remodeling. H2A has a Thr to Cys substitution at residue 120, where Cy5 is conjugated. H3.2 has a Cys to Ala substitution at residue 110.
Validation Data
Figure 1: DNA Gel Data
EpiDyne-FRET substrate resolved via native PAGE gel and
stained with ethidium bromide to visualize DNA.
Lane 1: Free DNA (100 ng).
Lane 2: Intact EpiDyne-FRET nucleosomes
(400 ng).
Figure 2: Protein Gel Data
Coomassie stained PAGE gel of proteins in EpiDyne-FRET
substrate (1 µg) demonstrates the purity of histones in the
preparation. Sizes of molecular weight markers and positions
of the core histones (H2A-Cy5, H2B, H3.2, and H4) are
indicated.
Figure 3: Nucleosome Remodeling Data
ACF1/ATP-dependent nucleosome remodeling reaction.
EpiDyne-FRET nucleosomes (15 nM) were incubated with ACF1
chromatin remodeler (EpiCypher
15-1013; indicated concentrations) in the presence or absence of 1
mM ATP. Upon the addition of ATP, reactions were immediately
read in an Envision Multilabel plate reader (PerkinElmer).
Data are presented as the mean of the Cy3/Cy5 ratio (N=2).
Technical Information
Purified recombinant mononucleosomes, (21.8 µg protein weight, 50 µg DNA+protein) in 10 mM Tris-HCl pH 7.5, 25 mM NaCl, 1 mM EDTA, 2 mM DTT, 20% glycerol. MW = 240,650 Da.
Application Notes
This product is a template for nucleosome remodeling assays using Cy3/Cy5 FRET or using the restriction enzyme DpnII to determine accessibility of GATC, which is masked in its native configuration (prior to remodeling).
