    摘要: Computer-implementable methods consistent with the present teachings can be used in the design of selective- and multiple-reaction monitoring experiments for the identification of proteins and peptides of interest. By determining candidate parent-daughter ion transition pairs and scoring the pairs based on their ability to be detected experimental design time can be reduced and with a more focused list of transition pairs more experiments can be run successfully in a given period of time.

    摘要: The present teachings provide methods for the development of a mass spectrometric based assay for a protein in a sample using parent-daughter ion transition monitoring (PDITM). In various aspects, the present teachings provide methods for developing a mass spectrometric based assay for a protein in a sample without the use of a standard for the protein. In various embodiments, the sample comprises proteolytic fragments of a protein which is present in low abundance in the physiological fluid from which it is derived.
