A New Patent Using Peptides

A patent has been published that describes new methods of manipulating plant stomatal development through artificially controlling how CRSP is expressing in plant cells.  The cleavage of epidermal patterning factor 2 (EPF2) by a serine protease CRSP is a key regulating mechanism in plant stomatal development.  A 30-mer EPF2 peptide, dual-tagged with DABCYL and EDANS, was synthesized by LifeTein to evaluate the protease activity of synthetic CRSP in a FRET assay.
