Dabcyl-LNKRLLHETQ-Edans Fluorigenic PEXEL peptide	Parasite	Others
Dabcyl-LNKRLLHETQ-Edans (Fluorigenic PEXEL peptide) is a biological active peptide. (This FRET substrate peptide for Plasmepsin V (PMV) is derived from the conserved Plasmodium Export Element (PEXEL) motif of Histidine-Rich Protein II (HRPII). PMV is an ER aspartic protease that recognizes and cleaves the RXL sequence within the PEXEL motif of proteins exported by human malaria parasite Plasmodium falciparum, allowing them to translocate into host erythrocytes.)

2Abz-SLGRKIQIK(Dnp)-NH2	Peptides	Others
2Abz-SLGRKIQIK(Dnp)-NH2 is a biological active peptide. (This peptide is a second complement component (C2), the physiological substrate for the proenzyme Cls, first complement component. The complement system is a central component of host defense but can also contribute to the inflammation seen in pathological conditions. The C1s protease of the C1 complex initiates the host defense pathway. This peptide employs 2Abz/Dnp FRET pair for quantitation of complement enzyme activity.)
