摘要: The pumps (Pn) are operated to transport individual reagent streams into the chip in a non-pulsatile, laminar flow regime at low flow rates permitting lows grading from 0 to as little as 5 nl/min with a precision of 0.1 nl/min. In the chip (MFC), the reagent streams are merged and the reagents mixed to form a reaction product. The reaction product can be measured at one or more detection points defined in the chip. Concentration gradients are continuously varied by continuously varying the flow rates respectively produced by the pumps according to predetermined flow velocity profiles.

摘要: Methods for characterizing a biochemical reaction and analysis of reaction products by establishing continuously variable concentration gradients of one or more reagents of the biochemical reaction are provided. Methods for determining mechanism of inhibition or activation, potency of inhibition or activation, or both of an enzyme inhibitor or activator, respectively, are also provided. The continuously variable concentration gradients can be established in a microfluidic chip.
