抗原的,指与抗原相关的,常用于描述免疫学中抗原的性质或特性。

用法要点

形容词用法

antigenic 主要用作形容词,修饰名词,描述与抗原相关的特性,如抗原性、抗原结构等。

• antigenic properties
• antigenic variation
• antigenic determinant

介词搭配

常与介词 to 连用,表示对某种抗原的免疫反应或特性,如 antigenic to a virus。

• antigenic to influenza
• antigenic to specific antibodies
• antigenic to the host

学术语域

antigenic 主要用于医学、生物学和免疫学等学术领域,描述抗原的免疫原性或变异,日常对话中较少使用。

• antigenic shift
• antigenic drift
• antigenic presentation

句型结构

常用于被动语态或复合形容词结构,如 be antigenic 或 highly antigenic,强调抗原的免疫反应性质。

• The protein is antigenic.
• It has low antigenic potential.
• This strain is highly antigenic.

基础例句

This vaccine is designed to be highly antigenic, so it triggers a strong immune response.

这种疫苗被设计成具有高抗原性,因此能引发强烈的免疫反应。

Doctors say the new virus strain is weakly antigenic, making it harder to detect.

医生表示,这种新病毒株抗原性较弱,因此更难检测。

In biology class, we learned about antigenic properties and how they affect immunity.

在生物课上,我们学习了抗原特性及其如何影响免疫力。

If a substance is antigenic, it can cause your body to produce antibodies.

如果一种物质具有抗原性,它就能促使你的身体产生抗体。

高级例句

The research focuses on antigenic variation in influenza viruses to improve vaccine efficacy.

这项研究专注于流感病毒的抗原变异,以提高疫苗效力。

Antigenic drift can lead to seasonal flu outbreaks, requiring updated vaccines annually.

抗原漂移可能导致季节性流感爆发,因此每年都需要更新疫苗。

In immunology, antigenic determinants are key sites where antibodies bind to antigens.

在免疫学中,抗原决定簇是抗体与抗原结合的关键位点。

The pharmaceutical company is developing a drug that targets antigenic escape mechanisms in cancer cells.

这家制药公司正在开发一种针对癌细胞抗原逃逸机制的药物。

常见错误

❌ 错误:This virus is antigen.
✓ 正确:This virus is antigenic.

antigen 是名词,意为“抗原”;antigenic 是形容词,意为“抗原的”。这里需要形容词来描述病毒的特性,所以用 antigenic。

❌ 错误:The antigenic of the protein is high.
✓ 正确:The antigenicity of the protein is high.

antigenic 是形容词,不能直接用作名词。应使用名词 antigenicity(抗原性)来表达“抗原的性质或程度”。

近义词辨析

immunogenic

immunogenic 强调能引发免疫反应的性质,而 antigenic 更泛指与抗原相关的特性;immunogenic 通常指物质本身能刺激免疫系统,antigenic 可描述更广泛的抗原特征。

The vaccine is highly immunogenic (引发强免疫反应), but its antigenic properties (抗原特性) vary by strain.

allergenic

allergenic 特指能引起过敏反应的物质,而 antigenic 是更广泛的术语,指任何能作为抗原引发免疫反应的物质;所有 allergenic 物质都是 antigenic,但并非所有 antigenic 物质都是 allergenic。

Pollen is allergenic (引起过敏) and also antigenic (作为抗原), but not all antigenic substances like vaccines are allergenic.
