New Applications for MMP Substrates

Leveraging AnaSpec's proprietary detection technologies, AnaSpec FRET-based MMP substrates were recently used in a double differential in vivo zymography study at the University of New Brunswick. The successful results demonstrate the breadth of applications in which AnaSpec's innovative products can be utilized.

A mixture of QXL™ 570/5-TAMRA-labeled Peptide I incorporating a red fluorophore, and QXL™ 520/5-FAM-labeled Peptide XIII incorporating a green fluorophore were used to detect differential breakdown of the two different MMP substrates in zebrafish. Peptide I was broken down mostly in the maturing myotome boundaries, whereas Peptide XIII was broken down much more strongly in the notochord sheath (Courtesy of Dr. Bryan Crawford, Univ. of New Brunswick, Fredericton, NB).

Synthetic FRET peptide substrates provide a reliable method for monitoring enzyme activity by following substrate cleavage. Through AnaSpec's innovative FRET technologies, the SensoLyte™line of assay kits offers detection of MMPs and other substrates at the industry's longest wavelengths. Through the innovative work of researchers such as Dr. Crawford, it is clear that the potential for new innovative applications of AnaSpec's FRET technologies has only just begun to be explored.
