[Abstract]  Glycosaminoglycans (GAGs) including chondroitin sulfate (CS), dermatan sulfate (DS), heparin (HP), heparan sulfate (HS) and keratan sulfate (KS) are linear, sulfated repeating disaccharide sequences containing hexosamine and uronic acid (or galactose in the case of KS). Recently, a keratan sulfate (KS) disaccharide [GlcNAc6S(β1-3)Galactose(β1-]-branched CS-E was identified from the clam species M. chinensis. Here, we report the isolation protocol for KS-branched CS from M. chinensis. [摘要]  包括硫酸软骨素(CS),硫酸皮肤素(DS),肝素(HP),硫酸乙酰肝素(HS)和硫酸角质素(KS)的糖胺聚糖(GAGs)是含有己糖胺和糖醛酸(或半乳糖 KS案)。 最近,从蛤蜊种群中鉴定了硫酸角质素(KS)二糖[GlcNAc6S(β1-3)半乳糖(β1 - ] - 支链的CS-E),这里我们报告了分离方案 用于来自中华猕猴桃的KS分枝CS。
【背景】在组织中发现GAG作为蛋白多糖(PG)糖缀合物的聚糖部分。 CS是由N,N-乙酰基-D-半乳糖胺(GalNAc)和葡萄糖醛酸(GlcA)的线性,硫酸化重复二糖序列组成的GAG型。另一种GAG类型的DS通过葡萄糖醛酸C5-差向异构酶对CS的作用进行生物合成,将其GlcA转化为CS差向异构体,艾杜糖醛酸(IdoA)。其他GAG类型HS和HEP由N,N-乙酰基-D-氨基葡糖(GlcNAc)和GlcA / IdoA的硫酸化重复二糖序列组成。 KS由GlcNAc和半乳糖的硫酸化重复二糖序列组成。其中,CS的结构变化,如硫酸化模式和岩藻糖基化,取决于物种和组织的来源。例如,具有结构[-4] GlcA(β1-3)GalNAc4S(β1-)(其中S表示磺酸盐残基)的A-单元是在哺乳动物或鸡气管软骨CS中发现的主要二糖,而C-具有结构[-4] ...

[Abstract]  Export of transcribed mRNAs from nucleoplasm to cytosol is an essential process for the translation of genes into proteins. This process is tightly regulated by nuclear pores, composed of about 30 nucleoporin proteins (Nups). Whether or not the mRNAs are able to be appropriately exported to cytoplasm is of an importance for understanding the role of Nups. Here, we describe a practical protocol to detect the intracellular localization of mRNAs in mesophyll cells of Nicotiana benthamiana (N. benthamiana). This protocol is based on poly (A) in situ hybridization method using an oligo d(T) probe conjugated with Alexa Fluor-488. [摘要]  将转录的mRNA从核质到细胞质的输出是将基因翻译成蛋白质的必要过程。 这个过程受到由约30个核蛋白(Nups)组成的核孔紧密调节。 mRNA是否能够适当地输出到细胞质对于理解Nups的作用是重要的。 在这里,我们描述一种实用的协议,以检测本地烟草的本底细胞中的mRNA的细胞内定位(<本宁顿烟草)。 该方案基于使用与alexa fluor-488缀合的寡聚d(t)探针的poly(a)原位杂交方法。 该方案基于使用与alexa="" fluor-488缀合的寡聚d(t)探针的poly(a)原位杂交方法。="">
