一般描述
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
o-Phenylenediamine dihydrochloride has been used:
- as a substrate for the eosinophil peroxidase (EPO) assay in bronchoalveolar lavage fluid (BALF)
- in cell adhesion molecule-enzyme immunoassay (CAM-EIA) to analyze the amounts of E-selectin induced by test compounds (LPS or solutions and materials) on endothelial cells
- in ultra-sensitive enzyme-linked immunosorbent assay (ELISA) to measure prolactin and luteinizing hormone (LH)
重悬
Dissolve one tablet in 0.05 M phosphate-citrate buffer, pH 5.0, to the desired concentration (typically an OPD concentration of 0.4 mg/ml is used). Add 40 μl of fresh 30% hydrogen peroxide per 100 ml of substrate buffer solution, immediately prior to use. Tablets are individually packaged in foil packets.

Transmission routes of noroviruses, leading aetiological agents of acute gastroenteritis, are rarely verified when outbreaks occur. Because the destination of norovirus particles being firmly captured by micro-organisms could be totally different from that of those particles moving freely, micro-organisms with

Our laboratory has concentrated on the possible regulation the benzamides and nicotinamides may have on the processes of DNA repair and apoptosis. Recent reports have suggested that both apoptosis and inflammation are regulated by the transcription factor NF-kappaB. We have

Throughout the reproductive cycle in rodents, prolactin levels are generally low. In some species, including rats, a prolactin surge occurs on proestrus with peak concentrations coinciding with the preovulatory luteinizing hormone (LH) surge. In mice, however, there are conflicting reports
