Recombinant Human CD19(His 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.RANTES还具有抑制某些HIV-1，HIV-2和Simian免疫缺陷病毒（SIV）的菌株的能力。Recombinant Human CD19(His Tag)

产品简介凝血酶是由大小分别为31KD和6KD的两条肽链通过二硫键组成的一种丝氨酸蛋白水解酶，可从动物血浆中利用已凝血酶原水解制得，可催化纤维蛋白原（fibrinogen）水解释放A肽和B肽，由此形成纤维蛋白单体，单体进一步聚合，在血小板、红细胞和白细胞等参与下形成血凝块，常用于诊断学中凝血化验、凝血因子检测、血液或血浆的脱纤维化等；另外，由于凝血酶切割序列专一，水解效率高，因此在分子生物学、生物化学或生物工程制药研究中也常作为工具酶用于重组融合蛋白（包含凝血酶识别位点）的特异性断裂。本品是从牛的血浆纯化制得，具有纯度高、比活高、不含有其他蛋白酶活性、灭活病毒、生产稳定性好等特点。该酶适切割位点：A-B-Pro-Arg-▼-X-Y（其中，A和B为疏水氨基酸，X和Y为非酸性氨基酸），常见的识别序列为：1.Leu-Val-Pro-Arg-▼-Gly-Ser。2.Gly-Arg-▼-Gly。产品信息规格1KU/2KURecombinant Cynomolgus CD44 Protein,His Tag糖苷酶 F (PNGase F)是一种酰胺水解酶，经过和平空间站伊丽莎菌克隆，主要由脑膜炎脓杆菌等革兰氏阴性菌分泌。

SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that also include MERS‑CoV and SARS-CoV-1. Coronaviruses are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M) and Nucleocapsid protein (N). The SARS-CoV-2 S protein is a glycoprotein that mediates membrane fusion and viral entry. The S protein is homotrimeric, with each ~180-kDa monomer consisting of two subunits, S1 and S2 .The RBD of SARS-CoV-2 binds a metallopeptidase, angiotensin-converting enzyme 2 (ACE-2). Before binding to the ACE-2 receptor, structural analysis of the S1 trimer shows that only one of the three RBD domains is in the "up" conformation. This is an unstable and transient state that passes between trimeric subunits but is nevertheless an exposed state to be targeted for neutralizing antibody therapy. Polyclonal antibodies to the RBD of the SARS-CoV-2 protein have been shown to inhibit interaction with the ACE-2 receptor, confirming RBD as an attractive target for vaccinations or antiviral therapy.  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。
