Starna DNA Quality Control Standard for DNACON 260/280 reference material

Starna’s DNA Quality Control Standard is an easy-to-use liquid vial (1.5 mL) that provides the company’s DNACON 260/280 reference material in a consumable format suitable for use in drop technology systems. The vial is produced in an ISO 17025- and ISO Guide 34-accredited environment and provides a NIST-traceable quality control standard to enable quick and reliable quality assurance of the DNA 260/280 nm measurement process.

The concentration is matched for use with the ultralow (less than 5 µL) and short path length (1 mm) volume measurement systems and is suitable for performing DNA purity evaluations in clinical and bioscience laboratories. The QC standard mimics the spectral characteristics of DNA solutions with respect to the 260/280 nm ratio.

The reference material is stable and durable because it is not DNA and overcomes the problem of DNA solutions being inherently unstable, with changes constantly occurring within the materials themselves. DNA-based QC materials for routine use are not a viable proposition for process verification as the chemistry of molecular and microbiological organic substances is complicated and the materials themselves are often difficult to characterise, handle, package, store and certify.
