Signal Enhancement Enables Study of Label-Free Proteins
MARSEILLE, France, Jan. 26, 2023 — Researchers at Institut Fresnel have developed a technique to detect the ultraviolet-autofluorescence signal in single proteins, opening the way for the label-free study of thousands of proteins whose natural fluorescence cannot be detected using existing technology. Though proteins are fluorescent in the UV because they contain tryptophan amino acids, most proteins have only one to five tryptophan — which is too few to provide a strong UV signal at the level required for label-free
