SEQUENCE TAG MICROARRAY AND METHOD FOR DETECTION OF MULTIPLE PROTEINS THROUGH DNA METHODS

摘要

Methods and reagents for simultaneously measuring the concentration of numerous proteins in a sample are described. The technique uses many antibody display phages that contain corresponding specific nucleic acid sequence tags. Binding between various proteins and antibodies is determined by simultaneous detection of the specific sequence tags using a microarray. This method is applicable even when the concentrations of different proteins differ by orders of magnitude as the nucleic acid sequence tags may be amplified.
