从RNA酶解液中分离5′-尿苷酸
Separation of Uridine 5′-Monophosphate from the Enzymatic Degradation Solution of RNA
【摘要】 采用2根强酸性阳离子交换柱、1根弱碱性阴离子交换柱和1根强碱性阴离子交换柱进行4柱串联,可以从RNA酶解液中分离得到5′-尿苷酸,而不混有其它核苷酸,并对离子交换树脂种类、树脂量、洗脱剂等作了进一步研究。结果表明,采用4柱串联分离5′-尿苷酸,其总收率达到92.1%、结晶纯度达到86%以上。
【Abstract】 Uridine 5′-monophosphate(UMP) could be separated from the enzymatic degradation solution of RNA with two strong acid cation exchange columns,one weak base anionic exchange column and one strong alkali anionic exchange column.UMP Obtained was not contaminated with other three ribonucleotides.The total yield of UMP achieved 92.1% and the purity of UMP crystal reached above 86%.The type of ion exchange resin,resin amount and eluent were further studied.
