ERBB3,又称HH3(人表皮生长因子受体3),是一种I型膜糖蛋白,是酪氨酸激酶受体ERBC家族的成员。ERBP家族成员作为表皮生长因子(LU)家族的生长因子的受体。在ERBP家庭成员中,因为它含有一个缺陷的激酶域。ERBB3在角化细胞、黑色素细胞、骨骼肌细胞、成肌细胞和雪旺细胞中都有表达。单体ERbb3是一种低亲和性的受体。ERBB3与ERBB2的异聚反应形成高亲和性受体复合物。与此相反,ERBB3同向聚合或异向聚合形成了一个低亲和性的结合物。因为ERBB3含有一个有缺陷的激酶域,ERBB2的激酶域负责通过异二重瓣受体启动酪氨酸磷酸化信号。研究发现,ERBB3细胞质区内的三个离散氨基酸信号对ERBB2的转导至关重要。ERBB3的细胞质域也包含6个一致的结合主题,用于调节P85磷酸酶3激酶(PI3K)的HS2领域,以及一个丰富的一致的结合主题。ERBB3的细胞质域也包含6个一致的结合主题,用于调节P85磷酸酶3激酶(PI3K)的HS2领域,以及一个丰富的一致的结合主题。ERBB3的细胞质域也包含6个一致的结合主题,用于调节P85磷酸酶3激酶(PI3K)的HS2领域,以及一个丰富的一致的结合主题。表达区间及表达系统重组的人HR3/ERBB3蛋白表达自于C-端的HK293细胞和AVI标记。里面有血清20-Thr643。分子量大约71.6FGF-18与FGF R2C,FGF R3C以及高尔基蛋白GLG1结合,并诱导星形胶质细胞和小胶质细胞。Recombinant Human M-CSF/CSF-1 Protein,His-Avi Tag
重组型TEV蛋白酶(rTEV)是经过基因工程改造和纯化后的重组蛋白酶,不仅保持天然TEV酶的功能活性,且在广谱的温度范围内表现出更强的稳定性和特异性。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EXXYXQ↓(G/S),切割位点在谷氨酰胺和甘氨酸/丝氨酸之间。普遍应用的七氨基酸序列为:Glu-Asn-Leu-Tyr-Phe-Gln↓-Gly。rTEV在pH7.0,30℃时可达活性,但在pH6.0-8.5和温度4-30℃范围内皆有活性(见表1),使得反应条件的选择可根据目的蛋白的情况而灵活变动。另外rTEV切割后也能利用其N端的6×His标签,通过Ni-NTA树脂去除,以达到纯化目的蛋白的目的。产品性质来源(Source)大肠杆菌外观(Appearance)无色透明液体比活力(SpecificActivity)5U/μL活性定义(UnitDefinition)在1×rTEVBuffer(50mMTris,pH8.0,0.1mMEDTA,1mMDTT)中,30℃反应1h,剪切>85%的3μg底物所需要的酶量定义为一个活性单位。纯化(Purification)Ni柱亲和纯化纯度(Purity)≥95%(bySDS-PAGE)产品组分运输与保存方法冰袋运输。Recombinant Mouse EPHA5 Protein,His Tag重组肠激酶为采用重组大肠杆菌分泌表达的高纯度、高活性、高特异的牛肠激酶,不含其他蛋白酶。

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.
