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.通过研究,CDNF可防止6-羟基多巴胺(6-OHDA)诱导的多巴胺能神经元变性,这可能对帕金森氏病有益。

Cas9核酸酶是一种向导RNA(guideRNA,gRNA)引导的核酸内切酶,可催化双链DNA的裂解。NLS-Cas9-EGFP在Cas9核酸酶的基础上进行改造,它在N端包含一个核定位信号(NLS),在C端包含一个EGFP和一个6X(His)序列。当Cas9以NLS序列表达时,Cas9RNP复合物在进入细胞后立即定位到细胞核。不需要体内转录或翻译,提高了效率。此外,与其他系统相比,EGFP标签可作为追踪或分类转染细胞的报告器,通过荧光细胞分选(FACS)富集所需基因组编辑的细胞群。它降低了在基因组编辑应用中与单细胞克隆和基因分型相关的人工和成本。产品特点如下:无DNA:没有外部DNA添加;高切割效率:NLS确保Cas9蛋白高效进入细胞核;低脱靶效应:Cas9核酸酶的瞬时表达提高了切割的特异性;节省时间:无需转录和翻译;减少劳动力:通过基于EGFP的FACS富集细胞群以进行所需的基因组编辑。C端His标签增加了融合蛋白检测方法的选择。可应用于:通过体外DNA切割筛选高效和特异性靶向gRNA。通过电穿孔或注射与特定gRNA结合时的体内基因编辑。通过基于EGFP的FACS富集细胞群以进行所需的基因组编辑。储存条件-25~-15℃保存,有效期1年。Recombinant Canine PDGFA Protein,His Tag
