Buffer P2 is a lysis buffer solution produced by Qiagen.It contains 1% sodium dodecyl sulfate (SDS) (w/v) to puncture holes in cellular membranes, and 200mM NaOH.It is used in conjunction with other resuspension buffers and lysis buffers to release DNA from cells, often as part of the alkaline lysis method of purifying plasmid DNA from bacterial cell culture.
The P1 centrifuge uses an aluminum rotor, and the P2 centrifuge uses a maraging steel rotor, [3] which is stronger, spins faster, and enriches more uranium per machine than the P1. In Pakistan, the Zippe-type centrifuge had a local designation and was known as Centrifuge Khan (after Abdul Qadeer Khan ). : 151 [ 10 ]
