What is the main application of the Protease Fluorescent Detection Kit?
The kit is primarily used for measuring protease activity and detecting protease contamination in biological samples.
How should the FITC-labeled casein substrate be stored?
It should be aliquoted into smaller volumes and stored at -20 degrees Celsius, protected from light.
What temperature is recommended for incubating the samples?
Samples should be incubated at 37 degrees Celsius in the dark for optimal results.
How is the proteolytic reaction stopped?
The reaction is halted by adding TCA solution and incubating again in the dark.
What type of control samples should be used?
It is recommended to run at least one control sample of trypsin with each assay to ensure proper assay performance.
Can the assay be performed in a 96-well plate?
Yes, a 96-well plate can be used for high-throughput analysis of multiple samples.
