This unit describes functional assays for measurement of bioactive IL-12 and ELISAs for measurement of IL-12 protein. The functional assays are based on the ability of IL-12 to stimulate proliferation of PHA-activated T lymphoblasts ("PHA blasts"). The ELISAs are technically simpler to perform than the functional assays, but cannot distinguish bioactive from inactive cytokine.
本单元描述了用于测量生物活性白细胞介素-12(IL-12)的功能测定法以及用于测量IL-12蛋白的酶联免疫吸附测定法(ELISA)。功能测定法基于IL-12刺激PHA激活的T淋巴母细胞(“PHA母细胞”)增殖的能力。ELISA在技术上比功能测定法更易于操作,但无法区分具有生物活性和无活性的细胞因子。
