The NRI provides state-of-the-art laboratories with modern equipment for experiments that require 1) pyrosequencing to conduct quantitative genetic analyses; 2) gene sequencing and gene expression analyses; and 3) genomic and bacterial DNA purification. Labs are outfitted with time- and effort-saving instruments that perform rapid, high-precision polymerase chain reaction (PCR) as well as sensitive and flexible sorting procedures. Within steps of each laboratory are centrally located shared facilities, including cell and tissue culture rooms, –80* C freezers, imaging suites, microscopy areas, animal housing, centrifuges and incubators. All labs are furnished with ample work and storage spaces, protective hoods, ventilation systems and power back-up.
