Cas9核酸酶是一種引導RNA引導的核酸內切酶,可以催化雙鏈DNA的裂解。這種靶向核酸酶是一種高精度的基因組編輯的有力工具。Cas9蛋白與CRISPR/Cas9系統的引導RNA(gRNA)成分形成一個非常穩定的核糖白(RNP)復合物。Cas9RNP復合物可以在進入細胞后,通過添加一個N端核定位信號(NLS),增加入核效率。YEASEN開發的NLS-Cas9核酸酶在蛋白的N端包含一個核定位序列(NLS),以增加入核切割效率。產品特點如下:無DNA:沒有外部DNA添加。安全性好:野生型Cas9蛋白,無標簽。可應用于:通過體外DNA切割篩選高效和特異性靶向gRNA。產品信息貨號11366ES60/11366ES76規格100μg/500μg來源重組Cas9來源于大腸桿菌物種化膿性鏈球菌標簽無分子量160KDa濃度10mg/mL(50μg);10mg/mL(100μg)

N-糖苷酶 F (PNGase F)酶活定義(UnitDefinition)1個酶活力單位指在10μL的反應體系中,37℃條件下1小時從10μg變性RNaseB中除去超過95%的碳水化合物所需要的酶量。儲存條件-15~-25℃保存,有效期1年。使用說明變性條件下蛋白質去糖基化1)在水中加入1μLBuffer1和目標糖蛋白(1-20μg),至終體積10μL;2)100℃溫度下煮沸10min使其變性,冰上冷卻,離心10秒;3)加入2μL的Buffer2、2μL的10%NP-40、6μL去離子水,總反應體積20μL;4)加入0.2~0.5μL的PNGase,輕輕混勻。在37℃孵育1-3h。非變性條件下蛋白質去糖基化1)在水中加入2μL的Buffer2和目標糖蛋白(1-20μg)至體積為20μL。2)加入0.5~1μL的PNGaseF,輕輕混勻。3)37°C孵育4-24h。注意:在變性條件下大多數底物能夠更好的去糖基化,在非變性條件下可能需要增加PNGaseF的量和延長孵育時間。人血清白蛋白(HSA)是脂類等物質的轉運載體,其主要生理功能是調節血漿pH值和維持血漿滲透壓。

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.Recombinant Human Complement Factor D/CFD (His Tag)
