Our goal was to find a new substrate that was acted upon only by LAL in DBS, thus avoiding the need to carry out 2 assays in parallel in the presence and absence of the LAL-specific
inactivator Lalistat-2 (5).

The residue was reconstituted in 0.5 ml of water and tested for the presence of the nNOS
inactivator. This material was compared to the original solution of tobacco extract.
A fluorometric assay for lysosomal acid lipase using DBS has been developed based on a 4MU fatty acid substrate and a covalent
inactivator of the lysosomal acid lipase, which enables the activity of this enzyme to be teased out of the total lipase activity from a collection of enzymes in blood (75).

Carboxypeptidase N (CPN), [6] also known as an arginine/lysine carboxypeptidase, kininase I, or anaphyla-toxin
inactivator, is a member of a larger family of zinc metallopeptidases (16).
