甲状旁腺素(PTH),又称副甲状腺素,是一种由甲状旁腺分泌的多肽激素, 通过对骨骼、肾脏和肠道的影响来调节血清钙浓度。PTH 影响骨重塑,而骨 重塑是一个持续的过程,随着时间的推移,骨组织会交替地被吸收和重建。 PTH 是在血清钙(Ca2+)水平较低时分泌的。PTH 间接刺激骨基质内破骨 细胞的活动,以释放更多的离子钙(Ca2+)到血液中,提高低血清钙水平。 PTH 主要由甲状旁腺的主细胞分泌,它是一种含有 84 个氨基酸的多肽,分 子质量约为 9500Da,是一种原激素,它的作用受到降钙素的反对。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有小鼠甲状旁腺素(PTH)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小鼠甲状旁腺素(PTH)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 Mouse PTH 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 Mouse PTH 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.
