Product Information
KE00323 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The CD200 ELISA kit is to be used to detect and quantify protein levels of endogenous CD200. The assay recognizes human CD200. An antibody specific for CD200 has been pre-coated onto the microwells. The CD200 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-CD200 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
CD200, also known as OX2, is a type I transmembrane glycoprotein that belongs to the immunoglobulin superfamily. It contains two extracellular immunoglobulin domains, a transmembrane and a cytoplasmic domain. CD200 is expressed on a variety of cell types, including thymocytes, B lymphocytes, a subset of T lymphocytes, follicular dendritic cells, neurons, and endothelial cells. CD200 binds to its receptor, CD200R, which is primarily expressed by myeloid and T cell lineage. The CD200-CD200R interaction plays a role in immunosuppression and suppression of anti-tumor immune responses.

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。
