  • Continuous flow methods for monitoring time dependent reactions
    Patent number: 7001716
    Abstract: Methods for monitoring time dependent reactions that comprise providing a flow channel, typically microscale in dimension, flowing at least two reagents into the flow channel and varying the flow rate of the mixture through the flow channel. By increasing and/or decreasing the flow rate of the reagent mixture from the point of mixing to the point of detection, one alters the amount of reaction time, allowing monitoring reaction kinetics over time.
    Type: Grant
    Filed: May 20, 2003
    Date of Patent: February 21, 2006
    Assignee: Caliper Life Sciences, Inc.
    Inventors: Samuel D. H. Chan, Ring-Ling Chien, Andrea W. Chow, Benjamin N. Wang
