The results demonstrated that α cyano ferulic acid used as a new matrix could effectively desorb and ionize different kinds of samples, such as proteins and peptides, oligosaccharides, polysaccharides and oligonucleotides. In analysis of dextrans the new matrix gave better results when comparing with the normally used DHB. In analysis of DNA d(T) 18 , the sample could be desorbed and ionized more efficiently even without sample purification, which is normally needed when using 3 HPA as a matrix.展开更多
文摘This paper reports for the first time an experiment designed in which synthesized α cyano ferulic acid used as a new matrix for the analysis of cytochrome c, trypsin, bovine serum albumin, β cyclodextrin, dextrans and DNA d(T) 18 . The results demonstrated that α cyano ferulic acid used as a new matrix could effectively desorb and ionize different kinds of samples, such as proteins and peptides, oligosaccharides, polysaccharides and oligonucleotides. In analysis of dextrans the new matrix gave better results when comparing with the normally used DHB. In analysis of DNA d(T) 18 , the sample could be desorbed and ionized more efficiently even without sample purification, which is normally needed when using 3 HPA as a matrix.
