Meaning and Usage

DEAE paper refers to a specific type of chromatography paper that has been treated with diethylaminoethyl (DEAE) groups. It is primarily used in laboratory settings for the separation and analysis of biomolecules, such as nucleic acids and proteins.

The frequency of use for "DEAE paper" is relatively specialized, primarily found in scientific and academic literature related to biochemistry and molecular biology. It is more commonly encountered in written contexts such as research papers, laboratory manuals, and educational materials rather than in oral speech.

Example Sentences

1. Researchers often rely on DEAE paper to purify their protein samples effectively.

2. Исследователи часто полагаются на бумагу DEAE для эффективной очистки своих белковых образцов.

3. The experiment failed because the DEAE paper was not correctly calibrated before use.

4. Эксперимент не удался, потому что бумага DEAE не была правильно откалибрована перед использованием.

5. By using DEAE paper, scientists can achieve higher resolution in their chromatographic separations.

6. Используя бумагу DEAE, ученые могут достичь более высокой четкости в своих хроматографических разделениях.

Etymology

The term "DEAE" comes from "diethylaminoethyl," which is a chemical descriptor indicating the presence of a diethylamino (a nitrogen-containing organic compound) and an ethyl group. The "paper" component refers to a cellulose-based medium used for chromatography.

Synonyms and Antonyms

Synonyms: - Chromatography paper (in a broader context) - Ion-exchange paper

Antonyms: - Non-chromatographic materials - Standard office paper (in the context of chromatography use)
