Intended use
This immunoassay kit allows for the in vitro quantitative determination of Human homovanillic acid,Homovanillic acid concentrations in
serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids.
Test principle
The ELISA is based on the competitive binding enzyme immunoassay technique. The microtiter plate provided in this kit has been
pre-coated with an antibody specific to Homovanillic acid, During the reaction, Homovanillic acid in the sample or standard competes with
a fixed amount of biotin-labeled Homovanillic acid for sites on a pre-coated Monoclonal antibody specific to Homovanillic acid. Excess
conjugate and unbound sample or standard are washed from the plate. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is
added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is
terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450
nm ± 2 nm. The concentration of Homovanillic acid in the samples is then determined by comparing the O.D. of the samples to the
standard curve.

文献和实验Human Xanthine Oxidoreductase Determination by a Competitive ELISA
Xanthine oxidoreductase (XO) catalyses the oxidation of hypoxanthine to xanthine and of the latter to uric acid. The enzyme is present in traces in most of human tissues, including plasma, being more abundant in milk, liver, and intestine (1).
调至 1μg/μl。 4. ELISA 检测：按试剂盒说明书完成板平衡、加样孵育、洗板、酶标抗体孵育、显色终止与读数，结合标准曲线得出 IFN-γ 浓度。 四、操作要点速记 1.组织样本新鲜处理，全程低温操作，裂解液现配现用； 2. 蛋白定量时标准品与样本同步孵育，稀释采用倍比稀释减少误差； 3. ELISA 实验需每次重绘标准曲线，洗板充分、严格把控显色与终止时间。 免疫检测试剂盒： 货号-规格 名称 abs510001-96T Human IL-2 ELISA Kit (Faster
