pBR322 DNA plasmid (New England Biolabs, UK) in PBS (100 ng, 20 µL) was incubated with 0.5 MBq (8 µL) [201Tl]TlCl3 for upto144 h. [201Tl] TlCl3, originally formed using chloramine-T (method 6), was neutralised with Na2CO3 (0.1 M). Controls included untreated plasmid in PBS and equivalent amounts of non-radioactive [natTl]TlCl3 (Sigma). After treatment, plasmid (50 ng in PBS) was mixed with 6× loading dye (16 µL total volume), loaded onto a 0.8% agarose gel containing 10 µL GelRed Nucleic Acid stain (Biotium, USA) and run at 100 V (400 mA, 50 W) for 40 min. Gels, imaged using a GelDoc-ItTS2 310 Imager system (BioRad, UK) coupled with a Benchtop UV transilluminator (UVP) and GelCam 310, were analysed by ImageJ, measuring supercoiled (intact DNA), relaxed circular (single strand breaks) and linear band (double strand breaks) percentages within a lane (n = 3–12) [33 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
