Flexible format allows user to choose between a colorimetric substrate or fluorogenic substrate
Can be used to screen inhibitors of caspase-1, study enzyme regulation and kinetics, or cleave target substrates
Inhibition of Caspase-1 by Ac-YVAD-CHO
The enzyme was incubated with the inhibitor for 10 minutes prior to addition of substrate. 30 U/well; [YVAD-CHO]=0.1 mM; [YVAD-pNA]=200 mM; 25° C
Kinetics of YVAD-pNA cleavage by Caspase-1
30 U/well; 25°C. Rates were obtained from the slopes of the initial, linear portion of plots of A405 vs. time. Curve and kinetic parameters derive from a non-linear least squares fit to the Michaelis-Menten equation (Marquadt algorithm).
Produced in E. coli. cDNA encodes residues identical to Asn120-His404 (C-terminus) at Genbank Accession No. M87507, except for an Asp381 to Glu change, introduced to stabilize the enzyme against autoproteolysis., ≥90% (SDS-PAGE) | Print as PDF
Produced in E. coli. Caspase-3 (CPP32; Yama; apopain) from human cDNA. The enzyme was cleaved and activated from the proenzyme, ≥95% (SDS-PAGE) | Print as PDF
