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.FGF-18與FGF R2C,F(xiàn)GF R3C以及高爾基蛋白GLG1結(jié)合,并誘導星形膠質(zhì)細胞和小膠質(zhì)細胞。Recombinant Human CEACAM-3 Protein,His Tag

α-凝血酶(α-Thrombin)是一種高度特異性的絲氨酸蛋白酶,由凝血酶原(Prothrombin,II因子)經(jīng)蛋白水解活化而來。它在凝血過程中起著非常重要的作用,不僅能夠促使纖維蛋白凝塊的產(chǎn)生,還負責提供反饋信號來尋找前輔因子:V因子和VIII因子。也可以用作血管收縮劑。在體內(nèi),活化的X因子(FactorXa)切割凝血酶原,釋放出活性肽并將凝血酶切割成具有催化活性的α-凝血酶。α-凝血酶由一條輕鏈(Achain)(Mw~6,000)和一條重鏈(Bchain)(Mw~31,000)通過二硫鍵連接而成。某些情況下,α-凝血酶會發(fā)生自溶生成β-凝血酶和γ-凝血酶。β-凝血酶由對α-凝血酶A鏈水解并切割含有B鏈糖基化位點的小片段(B1,B2)組合而成。除了用于凝血研究之外,α-凝血酶還常用來位點特異性切割融合蛋白?;蛑亟M時將凝血酶識別位點插入在目的蛋白與利于后續(xù)純化和/或表達的多肽或者蛋白之間,通過凝血酶切割表達的重組子即可釋放目的蛋白。凝血酶本身可通過親和層析技術(shù)快速去除。本品是由勻質(zhì)化的人凝血酶原經(jīng)由Xa因子,Va因子和磷脂活化而得,經(jīng)SDS-PAGE檢測確保凝血酶原的完全活化,并以NIH凝血酶的標準品為參考,提供的酶活力不少于3091NIHU/mg。(CDNF)也是一種新型神經(jīng)營養(yǎng)因子,對多巴胺能神經(jīng)元的強大活性,與神經(jīng)膠質(zhì)細胞系衍生的(GDNF)相當。
