Product Information
KE00608 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The human Kininogen 1 ELISA kit is to be used to detect and quantify protein levels of endogenous human Kininogen 1. The assay recognizes human Kininogen 1. An antibody specific for human Kininogen 1 has been pre-coated onto the microwells. The human Kininogen 1 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for human Kininogen 1 is added to detect the captured human Kininogen 1 protein. For signal development, 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
Kininogen 1 (also known as high molecular weight kininogen, HMWK, or Fitzgerald factor) is a multidomain glycoprotein found in the blood of most vertebrate. Kininogen 1 is a key component of the kallikrein-kinin system (KKS), which, together with coagulation factor XI, forms the contact activation system of blood coagulation (CAS), also known as the intrinsic pathway of coagulation. This system contributes to thrombin generation primarily under pathologic conditions and can operate independently from the tissue factor (TF) extrinsic pathway. Kininogen 1 and its fragments have been found to have various biological functions. For example, kininogen 1 can regulate leukocyte recruitment, and its domain 5 (kininostatin) can down-regulate endothelial cell proliferation and migration, inhibiting angiogenesis. Additionally, kininogen 1 has been identified as a potential biomarker for early detection of advanced colorectal adenoma and colorectal cancer.

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。
