| 预期应用 ELISA法定量测定人血清、血浆或其它相关液体中Pentosidine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Pentosidine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Pentosidine抗原、生物素化的抗人Pentosidine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Pentosidine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 human Pentosidine concentrations in serum and plasma.   Introduction Pentosidine is an advanced glycation end-product (AGE), formed by glycosylation and oxidation, that accumulates markedly in end-stage renal disease (ESRD). It has been speculated that AGE and carbonyl stress contributes to long-term complications such as cardiovascular disease (CVD) in ESRD patients.   Test principle This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for Pentosidine has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any Pentosidine present is bound by the immobilized antibody. An enzyme-linked monoclonal antibody specific for Pentosidine 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 Pentosidine bound in the initial step. The color development is stopped and the intensity of the color is measured. |
