DNA 260/280
Starna has introduced a new DNA Quality Control Standard in an easy-to-use liquid vial
(1.5 ml) that provides Starna’s DNACON 260/280 reference material in a consumable
format suitable for use in the DMV-Bio Cell.
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 ultra-low (less than 5ul) and short path
length (0.5 mm or less) volume measurement systems. The Starna DNACON 260/280
Quality Control Standard is ideal for performing DNA purity evaluations in clinical and
bioscience laboratories.
The new Starna DNACON 260/280 Quality Control Standard mimics the spectral
characteristics of DNA solutions with respect to the 260/280 nm ratio. The reference
material used by Starna is stable and durable because it is not DNA and overcomes the
problem of DNA solutions being inherently unstable, because the chemistry of molecular
and microbiological organic substances is complicated and the materials themselves are
often difficult to characterize, handle, package, store and certify. The stability of DNA
materials is always questionable because changes are constantly occurring within the
materials themselves.
STARNA GREEN
The use of aqueous dye solutions is an established and well-recognised method for the
validation of the absorbance scale and linearity of a spectrophotometer.
Starna Green is a mixed dye solution which appears green in colour to the human eye.
The concentration of the SG10 is matched for use with the ultra-low (less than 5ul) and
short path length (0.5 mm or less) volume measurement systems, and has spectral
characteristics that allow both the certification of the wavelength (257, 416, and 630 nm)
and absorbance scale in one discrete reference.
