一般描述
邻苯二胺(o-PD)是一种无色的非荧光分子。
邻苯二胺二盐酸盐（OPD）是一种显色底物，因为利用辣根过氧化物酶缀合物，因此可用于酶联免疫吸附试验（ELISA）程序。底物产生可溶的最终产物，其颜色为橙棕色，并且可以在450 m下通过分光光度计读取。可以用3N HCl或3M H2SO4终止OPD反应，并在492 nm处读取。
应用
在酶联免疫吸附试验(ELISA)中，邻苯二胺盐酸盐用作辣根过氧化物酶偶联二抗的底物。
重悬
将一片药片溶于 pH 5.0 的 0.05M 磷酸盐-柠檬酸盐缓冲液中至所需浓度（通常使用0.4mg/ml 的 OPD 浓度）。使用前，在每 100ml 底物缓冲溶液中加入 40 μl 新鲜的 30％ 过氧化氢，现配现用。片剂分别包装在箔包内。

Analysis of anti-malarial antibody responses has the potential to improve characterization of the variation in exposure to infection in low transmission settings, where conventional measures, such as entomological estimates and parasitaemia point prevalence become less sensitive and expensive to measure.
