降钙素(CT)是一种 32 个氨基酸的多肽激素,由甲状腺副滤泡细胞(也称为 C 细胞)分泌,在许多其他动物的超咽体中也是如此。它的作用是降低血钙(Ca2+),反对甲状旁腺激素(PTH)的作用。降钙素也被称为甲状腺降钙 素,它是由一个较大的前肽经蛋白酶裂解形成的,该前肽是 CALC1 基因(CALCA)的产物。它在功能上与 PTH 和维生素 D3 有拮抗作用。CALC1 基因属于相关蛋白激素前体的超家族,包括胰岛淀粉样前体蛋白、降钙素基因相关肽和肾上腺髓质素的前体。另外,血清中[Ca2+]的增加、胃泌素和五肽胃泌素都会导致降钙素的分泌。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有小鼠降钙素(CT)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降钙素(CT)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 CT 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 CT 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.
