tagged antigen (english) - meaning, definition, translation, pronunciation

Part of Speech

Noun

Phonetic Transcription

/ˈtæɡd ˈæntiˌdʒən/

Meaning and Usage

A tagged antigen refers to an antigen that has been labeled or tagged, often with a fluorescent dye or radioactive marker, to allow for the visualization, identification, or quantification of the antigen within a sample. This term is commonly used in immunology and molecular biology, particularly in research and diagnostic applications.

In terms of frequency of use, "tagged antigen" is more prevalent in written contexts, especially in scientific literature, research articles, and presentations related to immunological studies and laboratory techniques rather than in oral speech.

Example Sentences

1. The researchers prepared a tagged antigen to track the immune response in the experimental models.

2. Исследователи подготовили помеченный антиген, чтобы отслеживать иммунный ответ в экспериментальных моделях.

3. Using a tagged antigen allowed the team to visualize the binding events with greater accuracy.

4. Использование помеченного антигена позволило группе визуализировать события связывания с большей точностью.

5. The tagged antigen can be detected using fluorescence microscopy, making it an invaluable tool in biomedical research.

6. Помеченный антиген можно обнаружить с помощью флуоресцентной микроскопии, что делает его незаменимым инструментом в биомедицинских исследованиях.

Idiomatic Expressions

While the phrase "tagged antigen" itself does not frequently appear in idiomatic expressions, the concept of tagging and antigens is often used in scientific contexts that can offer metaphorical insights. Here are some related idiomatic expressions involving "tag" or "antigen":

1. Tag along - To accompany someone.
2. She decided to tag along to the conference, hoping to learn more about tagged antigens.

3. Она решила пойти на конференцию, надеясь узнать больше о помеченных антигенах.

4. Tag the follow - To denote or highlight something for further study or attention.

5. In the lab, we always tag the follow-up samples for analysis of tagged antigens.

6. В лаборатории мы всегда помечаем образцы для последующего анализа помеченных антигенов.

9. В нашей учебной группе, если у вас есть помеченный антиген, вы можете сказать: "Ты попался!" когда ваша очередь выступать.

Etymology

The word "tag" originates from the Middle English "tagge," which means to fasten or attach, while "antigen" comes from the combination of "anti-" (against) and "gene" (producing), meaning a substance that produces an immune response. This highlights the role of tagged antigens as entities that can be identified and targeted by the immune system.
