| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. | ||
| Formulation | The TNAA solution (0.5mg/ml) contains Phosphate buffered saline (pH7.4), 10% glycerol and 1mM DTT. | ||
Tryptophanase,also known as tnaA, catalyzes chemical reaction using 2 substrates which are L-tryptophanand H2O. tnaA protein's three products are indole, pyruvate, and NH3.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
