A turn-on fluorescent traceable linker based on N-sulfanylethylcoumarinyl amide (SECmide) has been developed as an advanced cleavable linker. It was successfully employed for the enrichment and selective visualization of a target protein in cell lysate. The results demonstrated that the SECmide-based traceable linker is potentially applicable to the identification of low molecular weight target proteins, a factor which has been problematic for a previously developed N-sulfanylethylanilide-based traceable linker.
