    Thermo Fisher dna polymerase i e coli
    Nicking enzyme-mediated labeling of open chromatin. a Nicking of crosslinked chromatin using varying amounts of Nt.CviPII. A 1% agarose gel showing differential nicking of HCT116 genomic <t>DNA</t> based on amount of nicking enzyme (10 U, 5 U, 2.5 U, 1 U, 0.3 U, 0 U). M is a DNA molecular weight ladder. b Open chromatin labeling in fixed HeLa cells using dNTPs supplemented with TexasRed-dATP. Top panel : labeling reaction performed in the presence of Nt.CviPII and DNA polymerase I. Middle panel : labeling reaction performed in the presence of DNA <t>polymerase</t> I only. Bottom panel : labeling reaction performed in the absence of Nt.CviPII and DNA polymerase I. TexasRed-dATP was included in all reactions. DNA staining was performed using DAPI ( blue ) and TexasRed stain ( red ) represents labeled OCSs. Magenta stain ( Merge ) represents the colocalization. c Labeling efficiency of OCSs in all three assayed conditions. The y-axis represents the ratio of the intensity of the red pixels to the intensity of the blue pixels ( OCS labeling efficiency ). d Dot blot showing labeling of open chromatin by Nt.CviPII nicking enzyme in both native and formaldehyde-fixed HCT116 cells. The level of labeling was revealed using HRP-conjugated goat anti-biotin antibody

    Article Snippet: Open chromatin DNA was labeled with biotin by incubating the nuclei in the presence of 2.5 U of Nt.CviPII (NEB R0626S), 10 U of DNA polymerase I (M0209S) and 30 μM of each dNTP including 6 μM of biotin-14-dATP (Invitrogen, 19524-016) and 6 μM of biotin-16-dCTP (ChemCyte, CC-6003-1) in 200 μL of 1× NEB buffer 2.
