Abstract: A dispersed mobile-phase countercurrent chromatography system is described in which solutes are carried by a stream of dispersed mobile phase solvent through a column, or array of serially-connected columns, of stationary phase solvent with which the mobile phase solvent is immiscible. Solutes carried along by the stream of dispersed mobile-phase solvent will be equilibrated between the mobile-phase solvent and the stationary-phase solvent. Because the mobile-phase is dispersed into mini-droplets much smaller in diameter than the column of stationary phase, the enhanced surface/volume ratio of the droplets expedites countercurrent equilibration of different solutes between the mobile-phase solvent and the stationary-phase solvent in accordance with the distribution-coefficients of the solutes between the two solvents.

Abstract: The present invention relates to the discovery that delivery of EGFR to cell surface requires EGFR-SAR1A binding. Thus, the invention provides a method for identifying inhibitors of EGFR-SAR1A binding, which can serve as therapeutic agents for treating conditions involving undesirable EGFR signaling. The invention also provides novel composition and its use that suppresses the specific binding between EGFR and SAR1A for the purpose of treating or preventing a condition involving undesired EGFR signaling.
