重组型TEV蛋白酶（rTEV）是经过基因工程改造和纯化后的重组蛋白酶，不仅保持天然TEV酶的功能活性，且在广谱的温度范围内表现出更强的稳定性和特异性。rTEV是一种用来切除融合蛋白上亲和标签的常用工具酶，具有很强的位点特异性，严格识别七氨基酸序列EXXYXQ↓(G/S)，切割位点在谷氨酰胺和甘氨酸/丝氨酸之间。普遍应用的七氨基酸序列为：Glu-Asn-Leu-Tyr-Phe-Gln↓-Gly。rTEV在pH7.0，30℃时可达活性，但在pH6.0-8.5和温度4-30℃范围内皆有活性（见表1），使得反应条件的选择可根据目的蛋白的情况而灵活变动。另外rTEV切割后也能利用其N端的6×His标签，通过Ni-NTA树脂去除，以达到纯化目的蛋白的目的。产品性质来源（Source）大肠杆菌外观（Appearance）无色透明液体比活力（SpecificActivity）5U/μL活性定义（UnitDefinition）在1×rTEVBuffer（50mMTris，pH8.0，0.1mMEDTA，1mMDTT）中，30℃反应1h，剪切>85%的3μg底物所需要的酶量定义为一个活性单位。纯化（Purification）Ni柱亲和纯化纯度（Purity）≥95%（bySDS-PAGE）产品组分运输与保存方法冰袋运输。UbcH7耗尽导致S期延长和增殖速率降低，提示它可能在细胞周期中起作用。Recombinant Mouse PLA2G1B Protein,hFc Tag

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.
