The Fluorescent Powerhouse: MCA as a Labeling Agent

A primary application of MCA is in the creation of fluorogenic peptide substrates作者：H Chi·2014·被引用次数：12—In this report we prepared variouspeptide-MCAs(4-methylcoumaryl-7-amides) related to histone tail and protein-substrates such as p53 and estrogen receptor-α.. In this context, MCA is covalently attached to a peptide sequence. This linkage often results in the fluorescence of the MCA moiety being quenched, typically through resonance energy transfer (RET) to an adjacent quencher, such as a 2,4-dinitrophenyl (DNP) group. When a specific enzyme cleaves the peptide bond, the MCA-containing fragment is released, and its fluorescence is restored.Mca-SEVNLDAEFR-K(Dnp)-RR, amide This increase in fluorescence signal directly correlates with enzyme activity, making it a powerful tool for quantifying protease activity.Description.
