chromatography

AQC (6-Aminoquinolyl-N-hydroxysccinimidyl carbamate) is a reagent used in HPLC for the fluorescence detection of amino acid or protein sequences. It reacts with primary and secondary amino acids to produce fluorescent derivatives, enabling the detection of amino acids at picomolar levels.

N-Hydroxysuccinimide (HOSu; 1-Hydroxy-2,5-pyrrolidinedione) serves as an activated ester widely employed in bioconjugation technologies. It is utilized for protein labeling with fluorescent dyes and enzymes, the development of chromatography supports, beads, nanoparticles, and microarrays, surface activation of glass slides, and the chemical synthesis of peptides [1].
