(A) Schematic representation of the use of IQF substrates in protease assays. (B) Structures of two donor molecules: ACC and MCA. Preliminary experiments allowed us to propose that ACC has a higher quantum yield; thus, substrates containing this donor moiety are more protease sensitive. ACC-Lys(DNP) is a new donor-acceptor pair for use in protease assays.
