"All the talk of mouse holes, through-the-night swapping of test tubes, mixing samples, and secret state agency involvement was the stuff of spy novels, not elite sport we all thought.
Briefly, gaseous ClNO was prepared by mixing samples of Cl2 and NO in a stainless steel cylinder and backfilling with He carrier gas.
"Ohm" shows them coming up with, and then leaving by the wayside, techniques of cutting, mixing, sampling, looping, layering and sequencing that would soon become commonplace in rock.
After mixing, samples were centrifuged and the clear supernatant was evaporated to dryness under a gentle stream of nitrogen (30°C).
Again, the experiments were performed both with and without mixing samples with the reference DNA.
The pharmacological studies were mostly of low quality using small samples, half had mixed samples of non-cancer and cancer patients and several were over 30 years old.
The utility and advantage of using pyruvate-labeled pre-mix samples and obtaining a high-resolution HNCA through Non-Uniform Sampling (NUS), in comparison to traditional HNCA spectra, becomes apparent even for a small protein like GB1.
The stick was placed into a specimen collection tube, the cap was screwed on tightly, and the tube was shaken vigorously to mix the sample and extraction buffer.
After boiling and thorough mixing, samples were centrifuged and DNA-containing supernatants were stored at –20°C until use.
Results from laboratory and field testing show that sample volumes of 20 can can be obtained from a depth of 8 m without mixing of sample and recharge water.
