Angiotensin I Converting Enzyme (ACE-2), also called ACEH (ACE homologue), is a dimeric, zinc-dependent metalloprotease of the ACE family that also includes somatic and germinal ACE. ACE-2 mRNA is found at high levels in heart, testis, and kidney and at lower levels in a wide variety of tissues. ACE-2 is the SARS-CoV and SARS-CoV2 Spike protein receptor in vivo, functions catalytically as a carboxypeptidase to cleave several substrates including angiotensins I and II, and acts as a partner for B0AT1-family amino acid transporters. Through these functions, ACE-2 has been shown to be involved in several diseases including SARS, COVID19, acute lung injury, heart disease, liver and lung fibrosis, inflammatory lung disease, and cardiopulmonary disease . Full length ACE-2 protein includes an extracellular region composed of a single N-terminal peptidase domain and C-terminal collectrin-like domain (CLD), a transmembrane domain, and a short cytoplasmic tail. The N-terminal peptidase region is required for binding to SARS-CoV and SARS-CoV2 spike proteins, while the CLD contains a region that promotes dimerization and association with amino acid transporters.Recombinant Mouse PGK1 Protein,His Tag
qPCR(定量聚合酶链式反应)检测结果的准确性可能受到多种因素的影响,以下是一些关键因素:1.**引物和探针设计**:引物和探针的设计质量对qPCR的成功至关重要。不合适的引物设计可能导致低特异性或效率低的PCR反应。引物的选择应考虑引物的长度、Tm值(解离温度)和GC含量,以确保其适用于特定的核酸模板。2.**模板质量和纯度**:模板的质量和纯度直接影响qPCR的结果。污染或降解的模板可能导致偏差或虚假阳性结果。使用质量高、纯度高的DNA或RNA样本是确保准确和可靠的qPCR结果的关键。3.**反应条件和缓冲液**:PCR反应条件,包括温度、离子浓度和缓冲液成分,必须严格控制。温度梯度、离子...
