Open circular plasmid, resulting from single strand nicks, usually migrates slower in agarose gels and forms (faint) bands above the supercoiled plasmid DNA band. Why would clumps occur following the addition of Buffer P2 when using LyseBlue Reagent in a plasmid preparation?

However, such plasmid preparation cannot be used for in-vitro transcription due to the contamination of RNases.

* The pMB1 origin of replication is closely related to that of ColE1 and falls in the same incompatibility group.

The buffer also prepares the DNA for binding to the column matrix. Adjust the pH to 7.0. For a detailed description on how to run and interpret an analytical gel, please see Appendix A in the QIAGEN Plasmid Purification Handbook: "Agarose Gel Analysis of the Purification Procedure", or visit this link.

Useful hints and information on optimizing plasmid preparations can be found at the QIAGEN Plasmid Resource Center. A high-copy plasmid should yield between 3-5 ug DNA per 1 ml LB culture, while a low-copy plasmid will yield between 0.2-1 ug DNA per ml of LB culture.

Adjust the volume to 1 liter with distilled water.

The low concentration of alcohol in the wash buffer eliminates non specific hydrophobic interactions, further enhancing the purity of the bound DNA. RNase A, which is added at the beginning of the procedure, digests the liberated RNA efficiently during the alkaline lysis.

For simple, visual assay results, the SARS-CoV-2 Rapid Colorimetric LAMP Assay Kit includes a color-changing pH indicator for detection of SARS-CoV-2 nucleic acid amplification.

If you notice that RNase A activity is substantially reduced, you can add fresh RNase A to your buffer. Why is this, and what are your suggestions to improve yield and purity?
