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CX3CL1受到促炎性刺激的上调,包括巨噬细胞,树突状细胞,内皮细胞,神经元,平滑肌,上皮细胞的细胞类型。Recombinant Mouse CD7 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 SF-20/IL-25在分子生物学、生物化学或生物工程制药研究中也常作为工具酶用于重组融合蛋白的特异性断裂。

甲醇代谢通路是毕赤酵母更标志性的生理特征,也是其实现外源蛋白可控表达的关键机制,只在甲醇诱导条件下特异性启动。自然状态下,毕赤酵母优先利用葡萄糖、甘油等常规碳源,此时甲醇代谢相关基因完全沉默,避免能量浪费。当培养基中只留存甲醇作为碳源时,菌株会快速启动关键代谢基因,开启甲醇分解代谢过程。其代谢关键流程为:甲醇在醇氧化酶作用下生成甲醛,再经脱氢酶催化生成甲酸,更终分解为二氧化碳与水,同时为菌体生长与蛋白合成提供能量。该通路中的AOX1、AOX2启动子具备极强的甲醇诱导特异性,且表达调控严谨,无甲醇时几乎无本底表达,添加甲醇后可快速启动下游基因高效转录。科研人员利用这一特性,将外源目的基因与AOX...
