卵泡刺激素(FSH)是一种促性腺激素,也是一种糖蛋白多肽激素。FSH由垂体前叶的促性腺激素细胞合成和分泌,它和黄体生成素(LH)在生殖系统中共同发挥作用。FSH是一个35.5 kDa的糖蛋白异构体,由两个多肽单元组成,即α和β。其结构与黄体生成素(LH)、促甲状腺激素(TSH)和人绒毛膜促性腺激素(hCG)的结构相似。LH、FSH、TSH和hCG糖蛋白的α亚单位是相同的,由96个氨基酸组成,而β亚单位则不同。这两个亚单位都是生物活性所必需的。FSH有一个111个氨基酸的β亚单位(FSH β),赋予其特定的生物作用,并负责与卵泡刺激素受体相互作用。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有大鼠促卵泡素(FSH)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促卵泡素(FSH)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 FSH 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 FSH 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.
