Tycho is designed to run quick and precise protein quality check experiments. Tycho uses intrinsic protein fluorescence to follow protein unfolding while running a fast thermal ramp, yielding results in 3min. A protein’s unfolding behavior is characterized by various parameters, most notably the inflection temperature (Ti). The Ti can be used to identify properly folded protein, to compare different batches, or to analyze the influence of storage/transport conditions on a protein. An absence of Ti would suggest that the protein is already unfolded and therefore most likely nonfunctional.
