It serves as an amine-reactive homobifunctional crosslinker and a cell fixative before SDS-PAGE, staining, or electron microscopy, making it suitable for a wide range of morphological studies. Glutaraldehyde is capable of efficiently crosslinking amine and hydrazine derivatives to proteins and other amine-containing polymers. Notably, in certain reactions, biotin hydrazides have been directly coupled to nucleic acids using glutaraldehyde, presenting a potential utility in conjugating fluorescent hydrazides and hydroxylamines to DNA. In histology studies, Glutaraldehyde is also employed to preserve tissue sections and prepare them for closer examination. 应用 戊二醛可用于以下研究: 制备高分辨光学显微镜和电子显微镜研究用的固定液(戊二醛+多聚甲醛+ NaPO4)。 研究山羊抗辣根过氧化物酶与碱性磷酸酶的偶联反应。 组成原代固定剂，用于保护酵母细胞在高锰酸盐固定过程中细胞质特性的恶化。 明胶，聚乙烯醇，和聚庚肽的交联剂。 特点和优势 Versatile and adaptable for wide variety of research applications Ready-made solution reduces the need for preparation time |
