(A) The eight-well imager is handheld and battery-operated for easy use (top) and can be used to image the six-member fluorescent library (bottom). We show FD-CF reactions expressing, from left to right, mCherry, mRFP1, dTomato, mOrange, YPet, and sfGFP. (B) The 96-well imager is also battery-powered and has a removable lid for easy use (left). In vitro biological programs can be imaged using our custom 96-well imager with similar performance as a laboratory imager (right). (C) The portable incubator accommodates up to 96 standard PCR tubes and has a removable, insulating lid for maintaining reaction temperature at its two set points, 30° and 37°C (left). Fluorescent protein yields using our incubator set at 30°C are at least 50% of those achieved using a laboratory incubator (top right) and produce fluorescence that is visible in our handheld eight-well imager (bottom right). Values represent averages, and error bars represent average errors of n = 2 biological replicates.
