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.猴痘病毒A30蛋白是病毒进入宿主与细胞-细胞融合过程中所需的包膜蛋白,被认为是猴痘病毒研究中的重要靶点。Recombinant Human MANF

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.  26Rfa, Hypothalamic Peptide, human,纯度:经SDS-PAGE和HPLC鉴定纯度大于98%。Recombinant Rat BD-4

Enterokinase,Recombinant,Expressed in E.coli大肠杆菌表达重组肠激酶(不带标签)注意事项1.本产品所讲述的缓冲体系需要自行配置。2.不建议37℃条件下酶切,可能会有非特异性酶切出现。3.在>200mM咪唑,或>200mMNaCl,或>5%甘油,酶切会受到影响。如果样品溶液中含有上述成分的一种或多种,为获得理想的酶切结果,请先将样品透析到25mMTris-HCl8.0缓冲液中,然后再进行酶切实验;若不方便透析,可将样品稀释到咪唑含量在100mM以下,NaCl浓度在50mM以下,甘油浓度小于5%以下进行酶切,酶的用量与蛋白比例不变;若干扰因素很多,且不便去除,需要适当增加酶量或延长酶切时间,有助于得到理想的酶切效果。4.磷酸盐对Enterokinase有很强的抑制作用,痕量的磷酸盐都会严重影响Enterokinase的活性,因此在酶切体系内不能存在磷酸盐。5.本品是具有高酶活力重组肠激酶,切割蛋白使用量少,可不考虑除去。后续如需去除重组肠激酶,可用阴离子交换树脂(如DEAE-FF)对其进行洗脱。推荐洗脱条件如下:平衡缓冲液:25mMTris-HClpH8.0洗脱缓冲液:25mMTris-HClpH8.0,含100mMNaCl6.蛋白酶切效果不好,可适当增加酶量,或适当延长酶切时间。Recombinant Human MANF
