Product Information
KE00148 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Haptoglobin ELISA kit is to be used to detect and quantify protein levels of endogenous Haptoglobin. The assay recognizes human Haptoglobin. An antibody specific for Haptoglobin has been pre-coated onto the microwells. The Haptoglobin protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for human Haptoglobin is added to detect the captured human Haptoglobin protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Haptoglobin(HP), also named as zonulin, is a plasma glycoprotein and belongs to the peptidase S1 family. As a kind of acute-phase response protein, serum Hp is mainly synthesized by hepatocytes and is widely distributed in the circulation in humans. The main physiological function of serum Hp is binding free haemoglobin released from red blood cell lysis and protecting tissues and vessels from oxidative damage. The level of Hp is a useful biomarker for some diseases diagnosis, such as Hepatocellular carcinoma, Pancreatic cancer, Type 2 diabetes mellitus, Diabetes kidney disease and so on.

FAQ
1、我的样本稀释液有限，如何处理稀释倍数较大的样本？
我们建议您对样本进行梯度稀释。例如，人血清样本需要1000000倍稀释时，您可以分3个梯度，每个梯度100倍，进行稀释：
第一步：取2 uL人血清样本，加入198 uL样本稀释液，混匀得到100倍稀释的人血清样本
第二步：取2uL 100倍稀释的人血清样本+ 198 uL样本稀释液进行稀释，混匀得到10000倍稀释的人血清样本
第三步：取2uL 10000倍稀释的人血清样本+ 198 uL样本稀释液进行稀释，混匀得到1000000倍稀释的人血清样本。
如果样本需要进一步稀释，您可以使用更多梯度。除了我们推荐的样本稀释液，不建议您使用其他溶液或者水稀释。如果您的样本稀释液仍然不足，请联系我们的客服为您提供更多样本稀释液。

文献和实验本文主要介绍 ELISA 试剂盒、实验样本、相关问题，帮助大家更好地开展实验 试剂盒 Q1：科研试剂盒与临床试剂盒的区别 ？ A1：临床试剂是经过权威机构认可的，如 FDA、CFDA 等；而科研试剂一般是厂家自主研制，不需要通过权威机构验证。 经营临床诊断类产品的机构需要取得《医疗器械经营企业许可证》；经营科研试剂的机构不需要此证件。 临床试剂盒一般仅用于检测人血清/血浆等较为单一的分泌性样本类型；科研试剂盒的样本检测种类、检测范围则比临床试剂盒宽广得多。但一般来说，临床试剂盒的质量

)，或者转化1 μmol的有关基团的酶量。 2) ELISA试剂盒检测原理 ELISA是以免疫学反应为基础，将抗原、抗体的特异性反应与酶对底物的高效催化作用相结合起来的一种敏感性很高的试验技术。由于抗原、抗体的反应在一种固相载体──聚苯乙烯微量滴定板的孔中进行，每加入一种试剂孵育后，可通过洗涤除去多余的游离反应物，从而保证试验结果的特异性与稳定性。在实际应用中，通过不同的设计，具体的方法步骤可有多种。即：用于检测小分子抗原或半抗原的抗原竞争法(图A)、用于检测抗原的双抗体夹心法(图B)等等。 抗体
