Each file contains data for all three GFP variants used in the study, i.e., GFP-standard (GFP-STD), GFP-negative (GFP-NEG) and GFP-positive (GFP-POS).

Each folder is named for the formulation data it holds. For example, GFP-NEG data in the L-histidine folder refers to data obtained from experiments using GFP-NEG formulated with L-histidine (full conditions described in the article).
