Replication timing by density transfer

easier to dilute a solution that's too dense than to make a too-dilute solution more dense!) CsCl solution : Use 1.28 g dry CsCl per gram of 10 mM Tris, 100 mM EDTA , pH 7.5. The T10 E100 should have a refractive index of 1.3395

Qiagen MIDI protocol

in the Beckman. Promptly pour supernatant into another round-bottom 13 ml polycarbonate tube and re-centrifuge at 20,000 x g for 15 min. While the centrifugation is happening, equilibrate a Qiagen-tip 100 (see next step). 7. To equilibrate the tip
