预期应用
ELISA法定量测定大鼠血清、血浆、组织匀浆、细胞培养物上清或其它相关液体中AQP1含量。
实验原理
本试剂盒应用双抗体夹心酶标免疫分析法测定标本中AQP1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AQP1抗原、生物素化的抗大鼠AQP1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AQP1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 AQP1 concentrations in cell culture supernates, tissue homogenates serum, and plasma.
Introduction
AQP1 is a polypeptide hormone produced in pancreatic beta-cells that belongs to the family of calcitonin gene-related peptides. There is a 20% sequence homology between AQP1 and calcitonin and 44% homology with calcitonin gene-related peptide. AQP1 and its fragments stimulate the proliferation of osteoblasts, inhibit bone resorption, and increase bone density and the amount of bone mass.
Test principle
This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for AQP1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any AQP1 present is bound by the immobilized antibody. An enzyme-linked monoclonal antibody specific for AQP1 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 AQP1 bound in the initial step. The color development is stopped and the intensity of the color is measured. |
