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.  Recombinant Human LILRA5/CD85f/ILT11 (His-Avi Tag)α-凝血酶(α-Thrombin)是一種高度特異性的絲氨酸蛋白酶,由凝血酶原經(jīng)蛋白水解活化而來。

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。N-糖苷酶 F (PNGase F)在酵母中重組表達,可以裂解由天冬酰胺連接的高甘露糖、雜合和復(fù)雜的寡糖糖蛋白。Recombinant Human Ephrin-A4/EFNA4 Protein,hFc Tag

CX3CL1還通過募集巨噬細胞以及通過募集和介導(dǎo)破骨細胞前體的粘附而導(dǎo)致傷口愈合。Recombinant Human Fc gamma RIIIA/CD16a (V176) (His-Avi Tag)

Bovine Thrombin,High Specific Activity,>2000 IU/mg 牛凝血酶(高活力,>2000 IU/mg)本品有效切割質(zhì)量比1:2000,通常在未做過預(yù)實驗的情況下建議在1:1000質(zhì)量比進行體系的優(yōu)化,即1mg的目的蛋白加入2U的酶(2000U/mg),使用時可用生理鹽水將酶配成100U/mL,有效消化緩沖液:20mMTris-HCl,含150mMNaCl,pH8.0。在20℃-37℃切割0.3-16h。注意:①具體反應(yīng)溫度可根據(jù)融合蛋白的性質(zhì)而定,如需要低溫保存的蛋白,可在4℃切割24h。②因為凝血酶會吸附在玻璃上,建議用塑料管分裝凍存(-20℃)凝血酶溶液。注意事項1.此凍干產(chǎn)品穩(wěn)定性好,2~8℃條件下保存3年,酶活力未有變化。室溫條件下保存1年,酶活力未有變化。2.本產(chǎn)品作科研用途。3.為了您的安全和健康,請穿實驗服并佩戴一次性手套操作。Recombinant Human Fc gamma RIIIA/CD16a (V176) (His-Avi Tag)
