Product Information
KE00011 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The IL28A ELISA kit is to be used to detect and quantify protein levels of endogenous IL28A. The assay recognizes human IL28A. An antibody specific for IL28A has been pre-coated onto the microwells. The IL28A protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for IL28A is added to detect the captured IL28A protein. For signal development, horseradish peroxidase (HRP)-conjugated antibody 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
IL28A, also known as IFNL2, is a cytokine distantly related to type I interferons and the IL-10 family. IL-28A, IL-28B and IL-29 are three closely related cytokines classified as type III IFNs, which share many of the biological effects of type I IFNs but may have fewer side effects due to a more selective receptor distribution. All three cytokines have been shown to interact with a heterodimeric class II cytokine receptor that consists of interleukin 10 receptor, beta (IL10RB) and interleukin 28 receptor, alpha (IL28RA). IL28A is believed to play a significant role in the antiviral immune defense in the intestinal epithelium.

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。
