当与酶活性重塑复合物如SMARCA4、SMARCA2和ACF(如EpiCypher货号15-1014、15-1015、15-1013)配对时,该产品提供核小体重塑的高通量荧光读数。EpiDyne®-FRET单核小体由在大肠杆菌中表达的重组人组蛋白(组蛋白H2A-Cy5、H2B、H3.2和H4各两种;accession numbers::H2A-P4908;H2B-O60814;H3.2-Q71DI3;H4-P62805)组装而成,该组蛋白由212个DNA碱基对缠绕,并携带5'Cy3、Widom 601核小体定位元件和重塑时暴露的DpnII限制性内切酶基序(GATC)[1]。H2A在残基120位处具有Thr-Cys取代,其中Cy5是共轭的。H3.2在残基110位处具有Cys-to-Ala取代。

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 Multilabelplate reader (PerkinElmer). Data are presented 

as the mean of the Cy3/Cy5 ratio (N=2).
