预期应用
ELISA法定量测定大鼠血清、血浆或其它相关液体中含量。
实验原理
雌二醇是体内主要由卵巢成熟滤泡分泌的一种天然雌激素，能促进和调节女性性器官及副性征的正常发育。
本试剂盒应用双抗体夹心酶标免疫分析法测定标本中雌二醇（E2）水平。用纯化的抗体包被微孔板，制成固相抗体，往包被单抗的微孔中依次加入雌二醇抗原、生物素化的抗大鼠雌二醇抗体、HRP标记的亲和素，经过彻底洗涤后用底物TMB显色。TMB在过氧化物酶的催化下转化成蓝色，并在酸的作用下转化成最终的黄色。颜色的深浅和样品中的雌二醇呈正相关。用酶标仪在450nm波长下测定吸光度（OD值），计算样品浓度。
Intended use
This immunoassay kit allows for the specific measurement of rat Estradiol (E2) concentrations in serum, and plasma.
Test principle
This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal
antibody specific for Estradiol has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any Estradiol present is bound by the immobilized antibody. An enzyme-linked monoclonal antibody specific for Estradiol is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells
and color develops in proportion to the amount of Estradiol bound in the initial step. The color
development is stopped and the intensity of the color is measured. |
