主要產(chǎn)品線

一、SPARCL™試劑盒

SPARCL™（空間近距分析試劑捕獲發(fā)光）檢測使用兩種特定的抗體；一種與HRP結(jié)合，另一種與二氫化吖啶結(jié)合，一種化學(xué)發(fā)光底物。當(dāng)HRP和二氫化吖啶結(jié)合的抗體與它們的靶生物標(biāo)志物結(jié)合時，加入過氧化氫（觸發(fā)溶液）后，HRP催化氧化鄰近二氫化吖啶分子，導(dǎo)致與生物標(biāo)志物濃度成比例的化學(xué)發(fā)光。遠(yuǎn)離HRP的二氫化吖啶分子不被氧化，因此不產(chǎn)生發(fā)光。這一原理可以開發(fā)一系列快速敏感的均相免疫分析方法。

典型的SPARCL™檢測不需要洗滌步驟，只需一次孵育，從開始到結(jié)束大約需要45分鐘。而ELISA需要1-4次孵育，1-3次洗滌步驟，需要2-4+小時。SPARCL™試劑盒需要一個能夠同時加樣和測量的光度計(jì)。Life Diagnostics提供一系列的SPARCL™檢測試劑盒。
