糖苷酶 F (PNGase F)酶活定义(UnitDefinition)1个酶活力单位指在10μL的反应体系中,37℃条件下1小时从10μg变性RNaseB中除去超过95%的碳水化合物所需要的酶量。储存条件-25~-15℃保存,有效期1年。使用方法1、变性条件下蛋白质去糖基化:1)在水中加入1μLBuffer1和目标糖蛋白(1-20μg),至终体积10μL;2)100℃温度下煮沸10min使其变性,冰上冷却,离心10秒;加入2μL的Buffer2、2μL的10%NP-40、6μL去离子水,总反应体积20μL;加入1-2μL的PNGase,轻轻混匀。在37℃孵育1-3h。2、非变性条件下蛋白质去糖基化:1)在水中加入2μL的Buffer2和目标糖蛋白(1-20μg)至体积为20μL。2)加入2~5μL的PNGaseF,轻轻混匀。3)37°C孵育4-24h。注意:在变性条件下大多数底物能够更好的去糖基化,在非变性条件下可能需要增加PNGaseF的量和延长孵育时间。注意事项1.PNGaseF建议搭配我司提供的配套缓冲液使用,按我司说明书建议的操作量配套缓冲液足够。如您由于使用体系造成配套缓冲液不足,可咨询当地销售进行购买FGF-18与FGF R2C,FGF R3C以及高尔基蛋白GLG1结合,并诱导星形胶质细胞和小胶质细胞。Recombinant Mouse PGK1 Protein,His Tag

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 Mouse PGK1 Protein,His Tag
