pDNA Analytical Standard pFix5 sc/oc (250 µg)

The Plasmid pFix5 standard is a 4.7 kb plasmid DNA, isolated from the E. coli microorganism and subjected to chromatographic purification. The standard comprises a specific ratio of plasmid DNA isoforms, with 29% ± 2% open circular (OC) and 71% ± 2% supercoiled (SC) forms.

This plasmid DNA standard serves a dual purpose: it is utilized for System Suitability Testing to ensure consistent performance of analytical equipment, and it is also employed in the preparation of a standard curve for quantitative assays.
