ERBB3,又稱HH3(人表皮生長因子受體3),是一種I型膜糖蛋白,是酪氨酸激酶受體ERBC家族的成員。ERBP家族成員作為表皮生長因子(LU)家族的生長因子的受體。在ERBP家庭成員中,因為它含有一個缺陷的激酶域。ERBB3在角化細胞、黑色素細胞、骨骼肌細胞、成肌細胞和雪旺細胞中都有表達。單體ERbb3是一種低親和性的受體。ERBB3與ERBB2的異聚反應形成高親和性受體復合物。與此相反,ERBB3同向聚合或異向聚合形成了一個低親和性的結合物。因為ERBB3含有一個有缺陷的激酶域,ERBB2的激酶域負責通過異二重瓣受體啟動酪氨酸磷酸化信號。研究發現,ERBB3細胞質區內的三個離散氨基酸信號對ERBB2的轉導至關重要。ERBB3的細胞質域也包含6個一致的結合主題,用于調節P85磷酸酶3激酶(PI3K)的HS2領域,以及一個豐富的一致的結合主題。ERBB3的細胞質域也包含6個一致的結合主題,用于調節P85磷酸酶3激酶(PI3K)的HS2領域,以及一個豐富的一致的結合主題。ERBB3的細胞質域也包含6個一致的結合主題,用于調節P85磷酸酶3激酶(PI3K)的HS2領域,以及一個豐富的一致的結合主題。表達區間及表達系統重組的人HR3/ERBB3蛋白表達自于C-端的HK293細胞和AVI標記。里面有血清20-Thr643。分子量大約71.6

糖苷酶F(PNGaseF)是一種酰胺水解酶，經過和平空間站伊麗莎菌克隆，主要由腦膜炎膿桿菌等革蘭氏陰性菌分泌。N-糖苷酶F(PNGaseF)在酵母中重組表達（比活性：100000U/mL），可以裂解由天冬酰胺連接的高甘露糖、雜合和復雜的寡糖糖蛋白。PNGaseF的切割位點為糖蛋白內側N-乙酰葡萄糖胺（GlcNAc）和天冬酰氨殘基之間的酰胺鍵，同時將酶解后蛋白上的天冬氨酰轉化為天冬氨酸。本產品帶his標簽，常應用于抗體及其相關蛋白完全去糖基化。另外，我司還提供其他類型的糖苷酶，包括酵母重組表達的N-糖苷酶F（比活性：750000U/mL），內切糖苷酶H，內切糖苷酶S。產品信息產品性質中文別名（Chinesesynonym）N-糖酰胺酶F；N-糖苷酶F英文別名（Englishsynonym）PNGaseF來源（Source）酵母重組表達分子量（Molecularweight）36kDa比活性（Specificactivity）100000U/mL緩沖液組分（Buffer）20mMTris-HClpH7.5,50mMNaCl,5mMEDTA,50%GlycerolIdeS 具有獨特的底物選擇性，可以作為工具酶應用于抗體類藥物或抗體融合蛋白藥物的結構表征分析。

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.  IdeS Protease全稱免疫球蛋白G降解酶是由人類致病菌釀膿鏈球菌產生并分泌至胞外的一種半胱氨酸水解酶。Recombinant Mouse Serpin F1/PEDF Protein,His Tag
