Antibodies specifically binding to IL-2 and uses thereof

The invention relates to the technical field of antibodies, in particular to an antibody specifically combined with IL-2 and application of the antibody. The antibody provided by the invention can specifically bind to IL-2, has no cross reaction with other interleukin and other cytokines, has high affinity to IL-2, and has excellent performance in quantitative detection of IL-2. An IL-2 detection kit based on the antibody can realize quantitative detection of IL-2 in different matrix samples, is not interfered by matrixes, has relatively high sensitivity, specificity, accuracy and precision, is simple and rapid to operate and low in cost, and has a relatively good application value in quantitative detection of IL-2. 本发明涉及抗体技术领域，具体涉及特异性结合IL-2的抗体及其应用。本发明提供的抗体能够特异性结合IL-2，与其它白细胞介素等细胞因子无交叉反应，且该抗体对IL-2具有高亲和力，在IL-2的定量检测中表现优异。基于该抗体的IL-2检测试剂盒能够实现不同基质样品中IL-2的定量检测，不受基质的干扰，具有较高的灵敏度、特异性、准确度和精密度，操作简单、快速，成本低，在IL-2的定量检测中具有较好的应用价值。
