Sodium Acetate Precipitation of Small Nucleic Acids

实验步骤   1.        Add 2 μl carrier to the nucleic acid solution and mix well. 2.        Add 1:10 volume of 3 M sodium acetate and mix thoroughly; for 230 μl of Lower Running Buffer, this will be 23 μl of 3 M

Assembly of Nucleosomal Templates by Salt Dialysis

Because it is convenient to assemble nucleosomal templates through salt dialysis, large amounts of chromatin complexes can be made easily and in a short amount of time. This unit includes instructions for the various salt dialysis schemes (step versus gradient

Ethanol Precipitation of DNA

% ethanol Measure the volume of the DNA sample. Adjust the salt concentration by adding 1/10 volume of sodium acetate, pH 5.2, (final concentration of 0.3 M) or an equal volume of 5 M ammonium acetate (final concentration of 2.0-2.5 M
