Meaning and Usage

An affinity column is a type of chromatography column used in biochemistry and molecular biology to separate molecules based on their specific interactions. Typically, it involves binding a target molecule to a solid matrix via an affinity ligand which ensures that the target is retained while other molecules are washed away.

In English, it is primarily used in scientific contexts, particularly related to biochemical research and laboratory procedures. As such, it is more frequently found in written form, such as in scientific papers, textbooks, and research articles.

Example Sentences

1. The researchers used an affinity column to isolate the protein of interest from the complex mixture.

2. Исследователи использовали аффинную колонну для изоляции интересующего белка из сложной смеси.

3. After passing the sample through the affinity column, we identified several potential binding partners of the target molecule.

4. После прохождения образца через аффинную колонну мы идентифицировали несколько потенциальных связывающихся партнеров целевой молекулы.

5. The development of high-performance affinity columns has greatly enhanced the efficiency of protein purification techniques.

6. Разработка высокоэффективных аффинных колонн значительно повысила эффективность методов очистки белков.
