DNA-binding DNA binding assay was performed by incubation of 25 nM performed FAM labeled 16 bp or 25 nM Cy5-labeled 228 bp DNA and indicated amounts of wild type or variants chromowedge CHD1 protein without w While the DNA-binding Ne, for GDC-0449 Vismodegib 90 is used min at room temperature in 10 L reactions The buffer for reactions of DNA binding is 10 mM Tris pH 7.8, 50 mM NaCl, 3 mM MgCl 2, 1 mM DTT, 5% glycerol and 0.5 mg / ml BSA. Bound and free DNA were incubated by electrophoresis on native acrylamide gel of 6% to 0.25 × TBE at 4 for 60 corrected at 100 volts. Fluorescence signal was measured with a Typhoon 9410 imager. ATPase ATP hydrolysis test was coupled with a test NADH, as described above. Briefly, reactions contained sliding buffer with 2.
5 mM ATP, 18 100 nM CHD1, 0.4 mg / ml NADH, 2.5 mM PEP and 5 units of PK / LDH. When present, mononucleosomes reconstituted on R788 a DNA fragment 206 base pairs or the same DNA fragment 206 base pairs only, were to be added to a final concentration of 200 nM, as shown in 1000. Shown for measurements of protein CHD1 N Δ in Figure 4C, we found that the concentration of nucleosomes at or above 200 nm, which were. The absorbance was measured every 25 seconds for 15 minutes using a microplate Leseger t, with the Change in A340 reports about the rate of oxidation of NADH.
