Each protocol published has its own advantages and limitation and the plasmid DNA obtained by different protocols vary in purity and yield. Many of these are the modification of the classical alkaline lysis method while the available rapid isolation methods employ different solid phase minicolumns. ...

Protocol: Culture Volume 30-35 ml 1.5 ml 500 ml 1. Centrifuge to pellet and add soln 1 on ice for 15-30 min. 3.5 ml 100 µl 20 ml 2. Add soln. 2, mix gently on ice for 5 min. 7 ml 200 µl 40 ml 3. Add soln 3, mix by inversion and leave on ice for 30-60 min...
Plasmid DNA isolation (i.e., plasmid preps, mini-preps, rapid DNA preps, among other procedures) remains a repetitious and tedious laboratory task. Plasmid DNA isolation from bacteria has traditionally been performed using the “alkaline lysis” method, in which bacteria are resuspended in lysis ...
Elution Plasmid DNA From HiBindTM DNA Maxi column: Optional: For maximal yield and high concentration of plasmid, see alternative protocol of elution on page 7. For fast elution, proceed step 12-13. 12. Further Drying The Column (Optional). Choose either of the methods below to further dry...
The small-scale mini preparation of plasmid DNA is commonly used to screen bacterial clones for the presence of recombinant DNA inserts. Here, we present a fast and simple protocol by Holmes and Quigley (1981) that allows the screening of a large number of colonies or small cultures for ...
The condensed DNA is then separated by centrifugation. The RCF required for separating plasmid DNA from isopropanol is much higher than that used in step 2 of this protocol, at 15,000×G (or more). The pellet will contain primarily plasmid DNA with some residual salt. Most of the salt ...
