预期应用
ELISA法定量测定人血清、血浆、细胞培养物上清或其它相关液体中resistin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resistin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resistin抗原、生物素化的抗人resistin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resistin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 Resistin concentrations in cell culture supernates, serum, and plasma.
Introduction
Resistin, a novel adipose-derived protein, has been proposed to cause insulin-resistant states in obesity. Resistin is produced by white and brown adipose tissues but has also has been identified in several other tissues, including the hypothalamus, pituitary and adrenal glands, pancreas, gastrointestinal tract, myocytes, spleen, white blood cells and plasma. Resistin antagonizes insulin action, and is down regulated by rosiglitazone and peroxisome proliferator-activated receptor gamma agonists. Resistin is elevated in patients with type 2 diabetes and may play a role in the vascular complications of this disorder. Recently, resistin has been discussed controversially as a missing link between obesity and insulin resistance.
Test principle
This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for Resistin has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any Resistin present is bound by the immobilized antibody. An enzyme-linked monoclonal antibody specific for Resistin 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 Resistin bound in the initial step. The color development is stopped and the intensity of the color is measured. |
