How do you store DTT?
Dissolve 1.5 g of DTT in 8 mL of H2O. Adjust the total volume to 10 mL, dispense into 1-mL aliquots, and store them in the dark (wrapped in aluminum foil) at -20°C (indefinitely).
Can DTT be stored at?
In lyophilized form, the chemical is stable for 12 months. Once in solution, store at -20ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles. Directions for Use: DTT is supplied as a lyophilized powder.
How long can DTT be stored?
Storage and Stability The crystalline powder is stable for at least 12 months at +2 to +8°C when stored in a glass container protected from moisture and light.
Is DTT stable at room temperature?
When stored at room temperature, DTT rapidly loses its reducing capability. DTT is not stable when stored in a solution form. Conditions to Avoid: Light, dust generation, exposure to air, heat.
Does DTT need to be frozen?
Definitely DTT is stable for years… But it is important to keep the tubes well closed and avoid freeze thawing cycles. It is therefore recommended to make small aliquots and store them at -20°C.
How long is DTT stable in solution at room temperature?
How long is it stable if shipped at room temperature? We can ensure stability for ~72 hours without significant degradation or oxidation.
Can DTT be frozen?
Does DTT degrade at?
DTT is hygroscopic and has sensitivity to heat. Incompatible with strong oxidizing agents, and decomposes at pH >7. 8.
Does DTT go off?
How long is DTT stable at 20c?
It is stable for years at -20oC.
Can you freeze DTT?
How do you dissolve a DTT?
To prepare a 1 M DTT solution, dissolve 1.55 g of DTT powder in 10 mL of deionized water (e.g. Water, nuclease-free, #R0581).
What is the use of DTT?
Thermo Scientific DTT (DL-Dithiothreitol; Clelands reagent) is used to stabilize enzymes and other proteins, which possess free sulfhydryl groups.
Is DTT a solid?
Dithiothreitol (DTT) is the common name for a small-molecule redox reagent also known as Cleland’s reagent….Dithiothreitol.

What are the storage conditions for DTT solution?
Storage conditions (working solution): A solution of DTT in Hepes buffer, pH 7.75 is stable for one week at 2 to 8 °C if the container is tightly sealed and the solution is protected from atmospheric oxygen by argon or nitrogen.
The dissolved DTT will increase the final volume to approximately 1.25 ml. Store lyophilized at 4ºC, desiccated. In lyophilized form, the chemical is stable for 12 months. Once in solution, store at -20ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.
What is the volatility of a DTT solution?
DTT has a lower volatility than that of other reducing agents such as b-mercaptoethanol. DTT is not stable in solution, thus only freshly-made DTT solutions should be used. To prepare 1 M DTT solution, dissolve 1.55 g of DTT powder in 10 mL of deionized water.
How do you make a DTT solution?
It forms a clear, colorless solution at 50 mg/mL in water. DTT has a lower volatility than that of other reducing agents such as b-mercaptoethanol. DTT is not stable in solution, thus only freshly-made DTT solutions should be used. To prepare 1 M DTT solution, dissolve 1.55 g of DTT powder in 10 mL of deionized water.
