Angiotensin I Converting Enzyme (ACE-2), also called ACEH (ACE homologue), is a dimeric, zinc-dependent metalloprotease of the ACE family that also includes somatic and germinal ACE. ACE-2 mRNA is found at high levels in heart, testis, and kidney and at lower levels in a wide variety of tissues. ACE-2 is the SARS-CoV and SARS-CoV2 Spike protein receptor in vivo, functions catalytically as a carboxypeptidase to cleave several substrates including angiotensins I and II, and acts as a partner for B0AT1-family amino acid transporters. Through these functions, ACE-2 has been shown to be involved in several diseases including SARS, COVID19, acute lung injury, heart disease, liver and lung fibrosis, inflammatory lung disease, and cardiopulmonary disease . Full length ACE-2 protein includes an extracellular region composed of a single N-terminal peptidase domain and C-terminal collectrin-like domain (CLD), a transmembrane domain, and a short cytoplasmic tail. The N-terminal peptidase region is required for binding to SARS-CoV and SARS-CoV2 spike proteins, while the CLD contains a region that promotes dimerization and association with amino acid transporters.泛素蛋白是一個76個氨基酸，高度保守的核和細胞質蛋白。Recombinant Human DKK-1,His

產品簡介凝血酶是由大小分別為31KD和6KD的兩條肽鏈通過二硫鍵組成的一種絲氨酸蛋白水解酶，可從動物血漿中利用已凝血酶原水解制得，可催化纖維蛋白原（fibrinogen）水解釋放A肽和B肽，由此形成纖維蛋白單體，單體進一步聚合，在血小板、紅細胞和白細胞等參與下形成血凝塊，常用于診斷學中凝血化驗、凝血因子檢測、血液或血漿的脫纖維化等；另外，由于凝血酶切割序列專一，水解效率高，因此在分子生物學、生物化學或生物工程制藥研究中也常作為工具酶用于重組融合蛋白（包含凝血酶識別位點）的特異性斷裂。本品是從牛的血漿純化制得，具有純度高、比活高、不含有其他蛋白酶活性、滅活病毒、生產穩(wěn)定性好等特點。該酶適切割位點：A-B-Pro-Arg-▼-X-Y（其中，A和B為疏水氨基酸，X和Y為非酸性氨基酸），常見的識別序列為：1.Leu-Val-Pro-Arg-▼-Gly-Ser。2.Gly-Arg-▼-Gly。產品信息規(guī)格1KU/2KURecombinant Mouse CD180 Protein,His Tagα-凝血酶（α-Thrombin）可以啟動XIII因子和血小板，或者用作血管收縮劑。

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%。
