ACF Chromatin Remodeling Enzyme Complex Description: Recombinant Drosophila ACF Chromatin Remodeling Enzyme Complex, assembled from Acf1-FLAG and ISWI produced in SF9 cells. ACF is an ATP-dependent chromatin remodeling complex that regulates nucleosome spacing.
ACF Chromatin Remodeling Enzyme Complex Formulation: ACF Complex at 0.18 mg/ml in 5.2 μl of 20 mM Tris HCl pH 7.9, 150 mM NaCl, 2 mM MgCl2, 0.2 mM EDTA, 10 mM beta-glycerophosphate, 0.01% NP-40, 0.2 mM PMSF, 0.5 mM benzamidine, 1 mM DTT, 15% glycerol, 2 μg/ml leupeptin, 1 μg/ml aprotinin, 0.4 mg/ml recombinant human insulin, 0.4 mg/ml 3x FLAG peptide. Molarity: 973 nM
ACF Chromatin Remodeling Enzyme Complex Storage and Stability: Stable for six months at -80°C from date of receipt. For best results, aliquot and avoid multiple freeze/thaws.
ACF Chromatin Remodeling Enzyme Complex Application Notes: This product is sufficient to perform 100 remodeling reactions using EpiDyne®-FRET substrate. A single reaction is defined as 10 μl containing [5 nM ACF Complex/ 20 nM EpiDyne®-FRET/ 50 μM rATP] and remodels to completion in <20 minutes. 5x ACF Remodeling Assay Buffer is included (100 mM Tris HCl, pH 7.5, 250 mM KCl, 15 mM MgCl2, 0.05% (w/v) BSA, 0.05% (v/v) Tween 20). For best results, aliquot ACF into single-use aliquots upon arrival. Avoid multiple freeze/thaw cycles.
