By contrast, the mucosa resected from the ulcer margin, including the granulation tissue, showed significantly higher DNA synthesis and higher DNA and RNA concentrations.

At that time, due to work such as that of Holger Hydén, RNA concentrations had indeed been shown to correlate with learning, so the idea was quite plausible.

In this case, the latent variable corresponds to the RNA concentration in a sample.

The target transcript frequency can then be simply computed by dividing transcript concentration by total RNA concentration.

RNA concentration was measured by spectrophotometry.

The level of transcripts for the constitutive gene product β-actin was quantitatively measured in each sample to control for sample-to-sample differences in RNA concentration.

One μl of RNasin was added to the suspension, and the RNA concentration was determined by spectrophotometry.

RNA concentration was evaluated by A 260 measurement and quality assessed by electrophoresis on a 1.5% agarose gel.

RNA concentration was determined spectrophotometrically.

The RNA concentration was determined spectrophotometrically by measuring absorbance at 260 nm.
