The tandem use of preparative two-dimensional polyacrylamide gel electrophoresis (2-DE) and electroblotting onto polyvinylidene difluoride membranes has been employed to rapidly isolate a number of proteins from a crude cell extract of a human colon carcinoma cell line (LIM 1863). The immobilized proteins were located by staining with Coomassie Brilliant(More)
This work presents a microfluidic system that can transport, concentrate, and capture particles in a controllable droplet. Dielectrophoresis (DEP), a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field, is used to manipulate particles. Liquid dielectrophoresis (LDEP), a phenomenon in which a(More)
