泛素化是通过三个酶促步骤实现的。在ATP依赖的过程中,泛素酶(E1)催化与泛素形成活性硫酯键,然后转移到泛素载体蛋白的活性位点半胱氨酸(E2)。泛素级联对特定底物蛋白的选择性依赖于E2结合酶(细胞中包含的相对较少)和泛素-蛋白连接酶(E3)之间的相互作用,迄今为止已经鉴定出600多种这种酶。E3s是一个大的,多样化的蛋白质组,其特征是几个确定的基序之一。这些包括HECT(与e6相关蛋白c端同源),RING(真正有趣的新基因)或U-box(没有Zn2+结合配体的完整补充的修饰的RING基序)结构域。而HECT E3s在泛素化过程中具有直接的催化作用,RING和U-box E3s促进蛋白质泛素化。 后两种E3类型充当适配器类分子。 它们使E2和底物足够接近,从而促进底物的泛素化。虽然许多RING-type e3,如MDM2和c-Cbl,可以单独发挥作用,但其他一些是作为更大的多蛋白复合体的组成部分,如后期促进复合体。综上所述,这些多面的特性和相互作用使E3s能够利用泛素-蛋白酶体系统,在真核生物的所有细胞中提供一种强大而具体的蛋白质机制。该筛选了11种常用E2结合酶,可以筛选具有E3连接酶活性的蛋白所匹配的E2酶.Recombinant Human CD7 (His-Avi Tag)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。

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.  

Dabigatranetexilatemesylate,又称甲磺酸达比加群酯,是可口服的凝血酶抑制剂,是一种抗凝药,通过竞争结合凝血酶的纤维蛋白特异结合位点,阻碍纤维蛋白生成,从而抑制血栓的形成。产品信息英文别名(EnglishSynonym)Dabigatranetexilatemesylate,Pradaxa,BIBR1048MS,Dabigatranetexilatemethanesulfonate中文名称(ChineseName)甲磺酸达比加群酯,达比加群酯甲磺酸盐靶点(Target)Thrombin通路(Pathway)Protease/MetabolicEnzyme--ThrombinCAS号(CASNO.)872728-81-9分子式(Formula)C35H45N7O8S分子量(MolecularWeight)723.84外观(Appearance)粉末纯度(Purity)≥98%溶解性(Solubility)溶于DMSO运输和保存方法-25~-15℃保存,有效期3年。使用方法【数据来自于公开发表的文献,供参考,具体使用浓度请参考相关文献,并根据自身实验条件(如实验目的,细胞种类,培养特性等)进行摸索和优化。】动物实验(体内实验)在体内,口服dabigatranetexilate在大10-50mg/kg)和恒河猴(1-5mg/kg)时间剂量依赖性地表现出抗凝效果。透明质酸酶,英文名称Hyaluronidase,一类能够降低体内透明质酸活性的酶的总称,结构上由4个相同亚基构成。

IdeS Protease全称免疫球蛋白G降解酶,酶活(Enzymeactivity)40U/μL酶活定义(UnitDefinition)在37℃条件下,反应30min,剪切>95%的1μg重组单克隆IgG所需要的酶量定义为一个活性单位。储存条件-25~-15℃保存,有效期1年。使用方法1.在消化液中加入适量IgG(加至5mg);2.在IgG样本中加入IdeS蛋白酶(每1μgIgG加入1个单位的IdeS);3.将样品置于37℃孵育30-60min。IdeS蛋白酶在中性pH或接近中性pH的缓冲中活性强。推荐反应缓冲是50mM磷酸钠,150mMNaCl(pH6.6),多数常见的生物缓冲也适用,比如Tris或PBS;注意:不在此pH范围(例如乙酸盐缓冲液)的缓冲也可能适用,但是孵育时间或酶量需要根据实际情况进行优化。注意事项1.IdeS不能识别切割小鼠IgG1/IgG2b,大鼠、猪、牛和山羊IgG,对小鼠IgG2a和IgG3具有中等酶切活性,酶切小鼠IgG2a和IgG3建议增加IdeS的用量(推荐用量为正常用量的5-10倍)。2.IdeS不能切割非IgG亚型的单抗分子,包括IgA、IgM、IgD和IgE。双碱性内切酶又称为Kex2蛋白酶、YSCF蛋白酶,在酵母体内Kex2蛋白酶负责加工killer toxin和α-factor的前体。Recombinant Human CD7 (His-Avi Tag)
