NI assays are also easily adaptable to automation, particularly newer ones that use a chemiluminescent sialic acid substrate instead of a fluorogenic substrate (31).
In this assay, a purified MMP-2 enzyme is incubated in the presence of a fluorogenic substrate with and without CAST.
Moreover, after injection of cRNA encoding [beta]-galactosidase, the levels of enzyme activity were measured using a fluorogenic substrate, revealing a peak of [beta]-galactosidase activity at 6 to 9 days; this activity was still detectable for at least 10 days after injection.
Van Diggelen and coworkers have shown that this type of mutation can be revealed if the assay with the fluorogenic substrate is carried out in the presence and absence of sphingomyelin; the wildtype enzyme shows stronger inhibition by the latter than the mutant enzyme (38).

Cell lysates containing 50 [micro]g of protein were incubated with a caspase-3 fluorogenic substrate (DEVD-AFC), or a caspase-9 fluorogenic substrate (LEHD-AFC), for 1 h at 37[degrees]C.
This novel method relates to the use of a thin matrix that contains blood in the interstices of its structure and the use of a rhodamine-based fluorogenic substrate that has a high quantum yield and is not consumed significantly during the time of the assay.
