GalNAcCPG,N-乙酰半乳糖胺(GalNAc),去唾液酸糖蛋白受体(ASGPR)配体
质量控制:95%+纯度级别:分析纯AR贮存方法:避光储存GalNAc-CPG允许合成siRNA-GalNAc缀合物。N-乙酰半乳糖胺(GalNAc)是一种定义明确的肝脏靶向部分,得益于其与去唾液酸糖蛋白受体(ASGPR)的高亲和力。GalNAcCPGallowsthesynthesisofsiRNA-GalNAclaced.N-acetylgalactosamine(GalNAc)isawell-definedlivertargetingpart,duetoitstosialicacidglycoproteinreceptor(ASGPR)withhighaffinity.通过将其直接与寡核苷酸结合或将其修饰到特定的递送系统作为靶向部分,GalNAc在核酸疗法的发展中取得了引人注目的成功。Directlybythecombinedwithfewnuclearwast,acidorthetargeteddeliverysystemaspartofthemodificationtothespecific,GalNAcinthedevelopmentofnucleicacidtherapyhasachievedremarkablesuccess.N-乙酰化的半乳糖胺(GalNAc)偶联修饰是当前最常用的小核酸药物递送系统。GalNAc是去唾液酸糖蛋白受体(ASGPR)配体,能以nM级高亲和性结合ASGPR,随后受体在网格蛋白介导的内吞作用下将GalNAc及核酸摄取进入细胞。GalNAc偶联修饰的优势在于偶联的核酸分子量较小,并且作用时效长达数月。但由于ASGPR仅在肝实质细胞特异性高表达,存在组织局限性。N-bofcoolgalactosamine(GalNAc)couplingmodificationisthemostcommonlyusedsmallnucleicaciddrugdeliverysystem.GalNAcistosialicacidglycoproteinreceptor(ASGPR)ligands,nMlevelhighaffinitytoASGPR,thenundertheactionofreceptorinclathrinmediatedendocytosisGalNAcandnucleicaciduptakeintothecells.GalNAccouplingmodifiedadvantageliesinthecouplingofthenucleicacidmolecularweightissmall,andtheeffectofagingformonths.ButasaresultofASGPRonlyhighspecificityintheliverparenchymacells,limitationsexistorganization.
