應用

盐酸胍溶液已被用作固定缓冲液,用于基因组分析中基因组DNA的提取。[1]

生化/生理作用

盐酸胍(Gnd-HCl)是一种高效的离液剂(chaotropic agent),作为变性剂被广泛用于RNA分离、球蛋白变性和蛋白质复性研究。它是一种合适的样品缓冲剂,可用于亲和纯化的蛋白质复合物的快速有效的洗脱,以及之后的蛋白质消化步骤。[2]由于其在低摩尔浓度下抑制胰蛋白酶活性,并且在与十二烷基硫酸钠(SDS)结合时有形成沉淀的倾向,盐酸胍不适用于蛋白质组学实验。[2]盐酸胍常用于从富含细胞外基质(ECM)‐的组织(包括骨骼、软骨、韧带和肌腱)中提取蛋白质。[3]

Exploring the tendon proteome is a challenging but important task for understanding the mechanisms of physiological/pathological processes during ageing and disease and for the development of new treatments. Several extraction methods have been utilised for tendon mass spectrometry, however different

Protein digestion is an integral part of the "shotgun" proteomics approach and commonly requires overnight incubation prior to mass spectrometry analysis. Quadruplicate "shotgun" proteomic analysis of whole yeast lysate demonstrated that Guanidine-Hydrochloride (Gnd-HCl) protein digestion can be optimally completed within
