Dtt shelf life
WebShe swears that it needs to be freshly bought and kept in a dry, airtight container at 4 °C. But we're much more slack and find most stuff keep for a while. Still. 23 years. Just buy fresh reagent. The answer is always "if in doubt buy fresh reagent". Your time is worth 100X more than the reagent, so do it right.

Dtt shelf life
Did you know?
DTT's half-life is 40 hours at pH 6.5 and 1.4 hours at pH 8.5 and 20 °C; its half-life decreases further as temperature increases. The presence of EDTA (ethylenediaminetetraacetic acid) to chelate divalent metal ions (Fe 2+, Cu 2+ and others) considerably increases the half-life of DTT in solution. [6] … See more Dithiothreitol (DTT) is the common name for a small-molecule redox reagent also known as Cleland's reagent, after W. Wallace Cleland. DTT's formula is C4H10O2S2 and the chemical structure of one of its See more DTT is used as a reducing or "deprotecting" agent for thiolated DNA.

It has a redox potential of −0.33 V at pH 7. The reduction of a typical disulfide bond proceeds by two sequential thiol-disulfide exchange reactions and is … See more DTT is unstable in ambient atmospheric conditions as it is oxidized by oxygen; DTT should be stored and handled under inert gasses to prevent oxidation. Dithiothreitol shelf life can be extended with refrigeration at 2–8 °C. Oxidation presents further … See more WebStorage 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 …
