使用分光光度計分析
DNA 或 RNA 純度分析時,
確保儀器工作正常是非常
重要的事。 Starna DNA/RNA 可追溯驗證參考物質
(DNACON) 是一種很穩定的溶液,模擬 260/280 nm的DNA和RNA之比例。
RM-DNA(永久密封參考物)隨附可信賴的驗證報告,
由
ISO/IEC 17025 認可
的
Starna 實驗室
執行驗證分析,
提供
列出預期 260/280 nm 比值和比值限制。,並可追溯至美國國家標準暨技術研究院(National Institute of Standards and Technology,

The importance of this reference is that it allows the user
to validate an instrument's performance in real time. When
measuring unknown samples the user can verify that the
instrument is working correctly by reading the validation standard
both before, during and after each run of unknowns.
When using a spectrophotometer which automatically calculates
the 260/280 ratio, place the DNA/RNA validation reference
in the spectrophotometer and run the instrument's routine for
the 260/280 ratio. If the ratio is valid when compared to the
certificate then the user can be assured that the instrument is
calculating the ratio correctly. In a spectrophotometer without an
automatic calculation feature, simply use the DNA/RNA validation
reference as a normal sample to validate your analytical
procedure.
With the vial references, the 5x concentration is suitable for the
NanoDrop™ instrument while the 10x concentration is suitable
for micro drop systems such as Jenway/Bibby.
Additionally, at 260 nm, results are approximately as follows:
Path length (mm) 5X Concentration 10X Concentration
0.2 0.1 A 0.2 A
0.5 0.25 A 0.5 A
1 0.5 A 1 A
10 5 A 10 A
