幽门螺旋杆菌,以前被称为幽门弯曲杆菌,是一种革兰氏阴性、嗜微、螺旋状(螺旋状)细菌,通常在胃中发现。该细菌于1982年由澳大利亚医生BarryMarshall和Robin Warren首次鉴定。它与胃、食道、结肠、直肠或眼睛周围组织的粘膜相关淋巴组织的淋巴瘤(称为所述器官的结外边缘区B细胞淋巴瘤)和胃内淋巴组织的淋巴瘤(称为弥漫性大B细胞淋巴瘤)有关。幽门螺杆菌感染通常没有症状,但有时会引起胃炎(胃部炎症)或小肠第一部分的溃疡。这种感染还与某些癌症的发生有关,发生率不到20%。 本试剂盒采用间接法酶联免疫吸附试验(ELISA)。往预先包被有小鼠幽门螺旋杆菌IgG(Hp-IgG)抗原的微孔中,依次加入样本、阳性对照、阴性对照、HRP标记的二抗,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幽门螺旋杆菌IgG(Hp-IgG)呈正相关。用酶标仪在450nm波长下测定吸光度(OD值),判断样本阴阳性。
This kit employs the indirect enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Mouse Hp-IgG antigen. The sample or standard is first added to the wells, followed by an HRP (horseradish peroxidase)-labeled secondary antibody. The procedure involves incubation and wash steps between each addition. TMB substrate is then added for color development. Under the catalysis of the peroxidase (HRP), TMB is converted into a blue product, which subsequently turns into a final stable yellow color upon the addition of an acid stop solution. The intensity of the yellow color is directly proportional to the concentration of Mouse Hp-IgG 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.
