褪黑素（melatonin），或称褪黑激素或美拉托宁，化学名为N-乙酰基-5-甲氧基色胺。5-羟色胺（又称为血清素）在N-乙酰基转移酶催化下与乙酰辅酶A反应转化为N-乙酰-5-羟色胺，然后N-乙酰-5-羟色胺再在乙酰血清素O-甲基转移酶催化下被S-腺苷甲硫氨酸甲基化为褪黑素。褪黑激素补充剂的副作用在小剂量、短疗程时是最小的。它们可能包括嗜睡（困倦）、头痛、恶心、腹泻、异常的梦境、易怒、紧张、不安、失眠、焦虑、偏头痛、嗜睡、精神运动性亢进、头晕、高血压、腹痛、烧心、口腔溃疡、口干、高胆红素血症。 本试剂盒采用竞争法酶联免疫吸附试验（ELISA）。往预先包被有大鼠褪黑素(MT)抗原的微孔中，依次加入样本、标准品、Biotin标记的抗体，HRP酶结合物，中间经过温育和洗涤，用底物TMB显色，TMB在过氧化物酶(HRP)的催化下转化成蓝色，并在酸的作用下转化成最终的黄色。颜色的深浅和样本中的大鼠褪黑素(MT)呈负相关。用酶标仪在450nm波长下测定吸光度（OD值），计算样本浓度。
This kit employs the competitive enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Rat MT antigen. The sample, standards, a biotin-labeled antibody, and an HRP enzyme conjugate are then added sequentially to the wells. The procedure includes incubation and wash steps between each addition. TMB substrate is used for color development. In the presence of the peroxidase (HRP) enzyme, TMB is catalyzed to produce a blue color, which is then converted into a final stable yellow color upon the addition of an acid stop solution. The intensity of the resulting yellow color is inversely proportional to the concentration of Rat MT in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader, and the concentration of the target analyte in the sample is calculated based on the standard curve.
