CD30,又稱KI抗原和Tnfrsf8,是一種120kdaI型跨膜糖蛋白,屬于tnf受體超家族。成熟的人CD30由一個361AA細胞外域(ECD)和六個富含半胱氨酸的重復,28AA跨膜段和188AA細胞質域。相比之下,小鼠和大鼠CD30缺乏90AA的ECD,并且只包含三個富含半胱氨酸的重復。在ECD的共同區(qū)域內,人CD30與小鼠CD30和大鼠CD30的序列認同率分別為53%和49%。人類CD30的交替剪接產生一個等形,包括細胞質域的C132AA。CD30通常在抗原細胞和B細胞上表達。但是,它在霍奇金氏病(紅-斯特恩伯格細胞上)、其他淋巴瘤、慢性炎癥中,以及自體免疫。CD30與CD30配體/tnfsf8結合,TH細胞、單核細胞、粒細胞和髓質胸腺上皮細胞上表達。產品性質別名CD30;CD30KI-1;CD30Lreceptor;TNFRSF8;D1S166EKi-1;CD30KI-1工會編號P28908-1表達區(qū)間及表達系統(tǒng)重組的人CD30/Tnfrsf8蛋白表達于在C-端有標記和AVI標記的HK293細胞。它含有……。分子量大約41.3公里。由于糖基化,蛋白質遷移到70-100kda基于三聯(lián)頁面結果。純度SDS-PAGE和高效液相色譜法測定的95%。鼠AFGF與人AFGF具有96%的氨基酸序列身份,因此它在鼠和人AFGF之間表現(xiàn)出相當大的物種交叉反應性。Recombinant Cynomolgus NKG2C/CD159c Protein,His Tag
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.
