Product Information
KE00053 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The HER2 ELISA kit is to be used to detect and quantify protein levels of endogenous HER2. The assay recognizes human HER2. An antibody specific for HER2 has been pre-coated onto the microwells. The HER2 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for HER2 is added to detect the captured HER2 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
HER2, also known as ErbB2 and Neu, is a member of the epidermal growth factor (EGF) receptor family. Overexpression of HER2 has been reported in numerous cancers, including breast, ovarian, lung, gastric, and oral cancers. It is a therapeutic target for the treatment of breast cancer and other carcinomas. HER2 is a 185-kDa transmembrane glycoprotein, the extracellular domain (ECD) of which can be cleaved from the cell surface by matrix metalloproteases and then released into the blood. Elevated serum HER2 levels are reported in 23% to 80% of patients with metastatic breast cancer. Raising serum HER2 levels have been correlated with indicators of poor prognosis and a poor response to chemotherapy.

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。
