Product Information
KE00254 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Human ACE2 ELISA kit is to be used to detect and quantify protein levels of endogenous human ACE2. The assay recognizes human ACE2. An antibody specific for human ACE2 has been pre-coated onto the microwells. The human ACE2 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody for human ACE2 is added to detect the captured human ACE2 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
Angiotensin-converting enzyme 2 (ACE2), a critical regulator of the renin-angiotensin system (RAS), belongs to the peptidase M2 family. It plays an important role in cardiovascular homeostasis by regulating vascular tone, fluid, and electrolyte balance. ACE2 functions as a carboxymonopeptidase hydrolyzing the cleavage of a single C-terminal residue from Angiotensin-II (Ang-II), the key peptide hormone of RAS, to form Angiotensin-(1-7) (Ang-(1-7)), which binds to the G-protein-coupled Mas receptor and activates signaling pathways that counteract the pathways activated by Ang-II. ACE2 is expressed in a variety of tissues, including the kidneys, testes, heart, and intestines, and is particularly enriched in lung epithelium. Recent studies have shown that increased ACE2 expression is likely to help prevent secondary fibrosis changes following COVID-19 pneumonia.

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。
