预期应用
ELISA法定量测定人血清、血浆或其它相关液体中人脂蛋白（Lpa）含量。

实验原理
脂蛋白a（LPa）是载脂蛋白a和载脂蛋白B100通过二硫键连接形成的特殊脂蛋白。血液中Lpa水平与心绞痛、早期动脉粥样硬化、心肌梗塞、脑溢血等有密切关系。Lpa是冠心病独立的危险因子，也是心脑血管疾病危险因素的指标。
本试剂盒应用双抗体夹心酶标免疫分析法测定标本中LPa水平。用纯化的抗体包被微孔板，制成固相抗体，往包被单抗的微孔中依次加入LPa抗原、生物素化的抗人LPa抗体、HRP标记的亲和素，经过彻底洗涤后用底物TMB显色。TMB在过氧化物酶的催化下转化成蓝色，并在酸的作用下转化成最终的黄色。颜色的深浅和样品中的LPa呈正相关。用酶标仪在450nm波长下测定吸光度（OD值），计算样品浓度。

Intended use
This immunoassay kit allows for the specific measurement of Lipoprotein (Lpa) concentrations in cell culture supernates, serum and plasma.

Test principle
This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for LPa has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any LPa present is bound by the immobilized antibody. An enzyme-linked monoclonal antibody specific for LPa is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LPa bound in the initial step. The color development is stopped and the intensity of the color is measured.
