The MRSEC Microfluidics Shared FacilitySeth Fraden, Dongshin Kim Brandeis University MRSECDMR-0820492 Collaborations with Facility Users During the academic year, Fall09 – Spring10, Dr. Kim, the facility director ,designed, built and tested devices for a number of MRSEC and outside users.(a)Microfluidic Device to Study of the Structure of Chromosomes (Dr. Wiggins). This is part of the “confined polymers” thrust. The origin of replication of the E-coli chromosomes is labeled with a parB-GFP fluorescent fusion protein to track the locus dynamics in live cells during chromosome replication. The cells are loaded using a permeation pump designed into the microfluidic device which is made from agarose gel so that drugs and growth media can be infused into the cells.
