Notes before starting
Add ethanol (96–100%) to Buffer PE before u (e bottle label for volume).
All centrifugation steps are carried out at 17,900 x g (13,000 rpm) in a conventional table-top microcentrifuge at room temperature.
Add 1:250 volume pH indicator I to Buffer PB. The yellow color of Buffer PB with pH indicator I indicates a pH of ≤7.5. If the purified PCR product is to be ud in nsitive microarray applications, it may be beneficial to u Buffer PB without
the addition of pH indicator I. Do not add pH indicator I to buffer aliquots.
1.Add 5 volumes Buffer PB to 1 volume of the PCR reaction and mix. If the color of

The color of the mixture will turn yellow.
2.Place a QIAquick column in S a provided 2 ml collection tube or into
z a vacuum manifold. For details on how to t up a vacuum manifold, refer to the QIAquick Spin Handbook.消防改造施工方案

4.To wash, add 0.75 ml Buffer PE to the QIAquick column S centrifuge for
30–60 s or z apply vacuum. S Discard flow-through and place the QIAquick column back in the same tube.
5.Centrifuge the QIAquick column once more in the provided 2 ml collection tube
for 1 min to remove residual wash buffer.
6.Place each QIAquick column in a clean 1.5 ml microcentrifuge tube.
7.To elute DNA, add 50 μl Buffer EB (10 mM Tris·Cl, pH 8.5) or water (pH 7.0–
8.5) to the center of the QIAquick membrane and centrifuge the column for
1 min. For incread DNA concentration, add 30 μl elution buffer to the center
of the QIAquick membrane, let the column stand for 1 min, and then centrifuge.
8.If the purified DNA is to be analyzed on a gel, add 1 volume of Loading Dye to
5 volumes of purified DNA. Mix the solution by pipetting up and down before
loading the gel.打喷嚏腰疼的原因
