| Main SKU |
During purification, storage or crystallization, even trace protease can break down proteins or peptides, and protein or peptide drugs need to be free of protease. Proteases are also key drug targets.
Kit Components
| Component | UPA1000 |
|---|---|
| 10 x Assay buffer | 5 ml |
| 1000 x Substrate | 50 µl |
Assay Principle
A fluorescence-labeled protein substrate is digested by proteases, which strongly increases its fluorescence at 535 nm (excitation 485 nm). The assay is continuous, so the signal can be read at several time points, and longer incubation (overnight or days) detects lower protease levels.
