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.  

N-糖苷酶 F (PNGase F)酶活定义（UnitDefinition）1个酶活力单位指在10μL的反应体系中，37℃条件下1小时从10μg变性RNaseB中除去超过95%的碳水化合物所需要的酶量。储存条件-15~-25℃保存，有效期1年。使用说明变性条件下蛋白质去糖基化1）在水中加入1μLBuffer1和目标糖蛋白（1-20μg），至终体积10μL；2）100℃温度下煮沸10min使其变性，冰上冷却，离心10秒；3）加入2μL的Buffer2、2μL的10％NP-40、6μL去离子水，总反应体积20μL；4）加入0.2~0.5μL的PNGase，轻轻混匀。在37℃孵育1-3h。非变性条件下蛋白质去糖基化1）在水中加入2μL的Buffer2和目标糖蛋白（1-20μg）至体积为20μL。2）加入0.5~1μL的PNGaseF,轻轻混匀。3）37°C孵育4-24h。注意：在变性条件下大多数底物能够更好的去糖基化，在非变性条件下可能需要增加PNGaseF的量和延长孵育时间。Kex2不能识别和切割单一碱性氨基酸即精氨酸或赖氨酸的羧基端肽键。

α-凝血酶（α-Thrombin）是一种高度特异性的丝氨酸蛋白酶，由凝血酶原（Prothrombin，II因子）经蛋白水解活化而来。它在凝血过程中起着非常重要的作用，不*能够促使纤维蛋白凝块的产生，还负责提供反馈信号来寻找前辅因子：V因子和VIII因子。也可以用作血管收缩剂。在体内，活化的X因子（FactorXa）切割凝血酶原，释放出活性肽并将凝血酶切割成具有催化活性的α-凝血酶。α-凝血酶由一条轻链（Achain）（Mw~6,000）和一条重链（Bchain）（Mw~31,000）通过二硫键连接而成。某些情况下，α-凝血酶会发生自溶生成β-凝血酶和γ-凝血酶。β-凝血酶由对α-凝血酶A链水解并切割含有B链糖基化位点的小片段（B1，B2）组合而成。除了用于凝血研究之外，α-凝血酶还常用来位点特异性切割融合蛋白。基因重组时将凝血酶识别位点插入在目的蛋白与利于后续纯化和/或表达的多肽或者蛋白之间，通过凝血酶切割表达的重组子即可释放目的蛋白。凝血酶本身可通过亲和层析技术快速去除。本品是由匀质化的人凝血酶原经由Xa因子，Va因子和磷脂活化而得，经SDS-PAGE检测确保凝血酶原的完全活化，并以NIH凝血酶的标准品为参考，提供的酶活力不少于3091NIHU/mg。Recombinant Mouse CXCL13/BCA-1 Protein,hFc Tag
