Epitope，也称为抗原表位，是指分子中可被免疫系统所识别并结合的位点，从以下三个方面进行说明：

1. 意义

Epitope是指分子中可被免疫系统所识别并结合的位点，是识别抗原的关键。因此，对于疫苗、免疫治疗等方面的研究与应用具有重要意义。

2. 应用

Epitope在疫苗开发中有广泛应用。疫苗的设计师可以通过研究目标病原体的表位特性，确定适宜的抗原表位，从而设计出可激发有效免疫反应的疫苗。除此之外，Epitope在临床诊断、药物研发等领域也有应用。

3. 研究

Epitope的研究在免疫学领域是一个重要的研究方向。针对不同的抗原，科学家们利用各种技术手段来筛选和鉴定表位，同时也在研究表位和免疫反应、表位识别和免疫逃逸等方面做了大量的工作。

以下是5个中英例句：

1. The team identified a specific epitope on the virus that triggered an immune response. （研究团队确定了一种病毒上的特定表位，该表位能够引发免疫反应。）

2. The antibodies can recognize and bind to the epitope on the virus suce. （抗体能够识别并结合病毒表面的抗原表位。）

3. Epitope mapping is a useful tool for understanding the molecular basis of immunity. （抗原表位映射是理解免疫分子基础的有用工具。）

4. The predicted epitopes were tested in vitro and showed strong binding to target receptors. （预测的抗原表位在体外进行了测试，表现出了对目标受体的强结合能力。）

5. The identification of novel epitopes may lead to the discovery of new theutic targets. （新的抗原表位的发现可能会导致新的治疗靶点的发现。）

中文翻译：抗原表位

读音：[ptp]

例句：

1. 这个疫苗包含了许多不同的抗原表位，可以提供广泛的保护作用。

This vaccine contains many different epitopes, which can provide broad protection.

2. 科学家通过研究病毒的抗原表位，设计出了一种新的疫苗。

Scientists designed a new vaccine by studying the epitopes of the virus.

epitope的意思是"抗原决定基、抗原决定区"，在日常中也代表"抗原表位"的意思，单词读音音标为['epitup]，epitope常被用作名词，在《中小学生词典》中，共找到96个与epitope相关的例句。

Epitope的释义

1.抗原决定基

例句:Peptide Mapping Analysis of Recombinant Human Neu Epitope Peptide 12 by Pepsin Digestion (重组人纽表位肽12的胃蛋白酶切肽图分析方法的研究)

2.抗原决定区

例句:Fusion of multi-epitope not only enhances the sensitivity and specificity, but also prevent from neglect to detection the CMV antibodys. (多抗原组合不仅能增加敏感性和特异性，还可以有效地防止漏检。)

3.抗原表位

例句:And I was thinking that your body hated it, at the time, because we are very immune to this. This is called alpha-gal epitope. (同时我也在想你的身体对之十分痛恨。因为我们对此免疫。这被称为alpha-gal抗原决定基。)

4.免疫、抗原表位

例句:And the specific barrier is a specific epitope called the galactosyl, or gal epitope. (翻译:这种特别的障碍是由 特殊的抗原决定基所导致 这种抗原决定基就是”半乳糖基“ )

用法及短语

epitope一般作为名词使用，如在discontinuous epitope([医]conformation-dependent epitope)、epitope identification(表位鉴定)、epitope library([医]表位文库)等常见短语中出现较多。
