Lab Facilities
The Johnson group occupies a contiguous 6-room, 3,151 sq. ft. laboratory complex that contains two hoods and the usual utilities. One room includes a 180 sq. ft. walk-in cold room and a 109 sq. ft. dark room for photocrosslinking and photosensitive preparations. A spectroscopy lab houses the four spectrofluorimeters and two lasers.
