Patent 8715934 was granted and assigned to Johns Hopkins University on May, 2014 by the United States Patent and Trademark Office.
Modulation of the viscosity of the oil phase of a microemulsion used for amplification of DNA on a bead increases the homogeneity of product beads and the amount of amplified DNA per bead. Moreover the number of separate microemulsion populations that can be formed in parallel is increased using multi-well plates and mixer mill disruptor machines designed to lyse biological samples.
