摘要
建立了灵敏的酶标双抗体夹心法测定血清可溶性IL-2受体(sIL-2R)。主要步骤为以单抗包被,加入待检抗原,再加多克隆兔抗IL-2 R血清作用,最后加酶标羊抗兔示踪并放大其反应。本法简便、重复性好、灵敏度达100u/ml.可适用于临床与基础研究。
In this work, a simple and sensitive assay for soluble IL-2 receptor (sIL-2R) was established. The main procedures are as follows: the microplate was coated with anti-Tac monoclonal antibody (McAb); after sIL-2R in samples bound with the McAb, the rabbit anti-IL-2R serum was added;and HRP-goat anti-rabbit IgG was used to display and amplify this binding. The sensitivity of this method is about 100u/ml, which is near that in 'Cellfree IL-2 Receptor Test Kit'.
