Ac-Ala-Asn-Trp-AMC (Ac-ANW-AMC)
By TAKASHI SHIMADA on 05/02/2020

S-320 hydrolysis confirmation by LCMS-SRM
S-320: 1 uM
i20S: 15 nM
PA28a: 150 nM
Reaction: 37 °C for 5 h
1:S-320 Ac-ANW-AMC (589.15>414.15)
2:Free AMC (176.25>120.00)
3:S-320 Ac-ANW-COOH (432.20>319.15)

Ac-Ala-Asn-Trp-AMC (Ac-ANW-AMC)
By TAKASHI SHIMADA on 05/02/2020

Ordinate: fluorescent count, Em 345/Ex 445
Em band path: 9 nm
Ex band path: 20 nm
Horizontal: time [min]
Temp: 37 °C
S-320: 5, 25, 50, and 100 uM
i20S: 100 ng per assay (100 uL)
The linearity of the kinetics was confirmed, and the fluorescence intensity increased in a concentration-dependent manner. But it is considered that the saturated level has not been reached using this condition. Probably it could be a low amount of i20S.
