KingFisher PlasmidPro processor performance data

Automated vs. manual plasmid DNA isolation and purification

The KingFisher PlasmidPro system consistently achieves high pDNA concentrations, exceptional elution volumes, and expected total yields, helping ensure reliable and reproducible results. Additionally, the system produces desired A260/A280 and A260/A230 purity ratio values, and preserves a high percentage of supercoiled form, indicating the integrity of the purified DNA. With its exceptional performance, the automated system is an excellent solution for researchers seeking efficient and high-quality maxi-scale plasmid DNA purification.

Figure 1. Gel image and supercoiled determination of purified pDNA. (A) Representative samples from Plasmid C (6.6 kb) in lanes 1–15 were purified using the KingFisher PlasmidPro instrument and compared to pDNA from a manual column-based kit in lanes 16, 17, and 18 run in 1% agarose gel. L1 is an Invitrogen linearized dsDNA ladder and L2 is the supercoiled pDNA ladder. The gel image shows that the supercoiled pDNA is the predominant form at 6.6 kb. (B) Densitometry analysis was performed with purified pDNA samples run on an agarose gel using the iBright Imaging and Analysis Software. Data represents the percent supercoiled pDNA from a subset of samples analyzed using the KingFisher PlasmidPro Maxi Processor. The box plot represents the distribution of data. Each dot represents an individual purification process. N is the number of purified samples from each plasmid size. The results show an average supercoiled pDNA at >80% for all three plasmid sizes. The percent supercoiled is comparable to the manual process for each plasmid B, C, and D at 88%.
