Moreover, the slight shifts in core levels, called chemical shifts, can be used to differentiate atoms of the same element in different environments, either within one molecule or in a mixed sample.

The mixed sample with both Tester and Driver cDNA can be heated to about 95C to denature the strands.

If your goal is to have a purified sample of a specific isotope, you are better off starting with a mixed sample and separating out the isotope you desire.

This suggests that the sensitivity and specificity of using mixed samples is approximately half that of individual profiles.

Replacing traditional PCR with COLD-PCR for these downstream assays will increase the reliability in detecting mutations from mixed samples, including tumors and body fluids.

Better than conventional PCR for the detection of mutations in a mixed sample.

Oversaturation can be a problem when analyzing mixed samples.

It was also difficult to determine a DNA profile for mixed samples, such as a vaginal swab from a sexual assault victim.

If the mixed sample is not passed through the converter, the ozone reaction produces activated NO[ ] only in proportion to the NO in the sample.

It is clearly a mixed sample of young and old, large and small - meaning several females and several males.
