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，不仅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 Betacellulin猴痘病毒（Monkeypox Virus, MPXV）属于正痘病毒属。一般来说，同属病毒具有相似的生物学特性。

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.  Recombinant Human NKG2A&CD94 Protein,hFc-Flag Tag
