does anybody have data about the stability in years of taq polymerase stored at -20 degree, thank you
¡Much longer than expiry date!. The only condition is keeping it really at -20ºC, preventing removing it from the freezer repeatedly.
We made the same experience like Luis, if the Taq is in the original buffer and was not subjected to thawing-freezing cycles, it will be stable for years in the freezer.
If you did not freeze and thaw the stock solution repeatedly, it will be stable for years.
Hello, I would like to model a channel but I have to consider different cases. I need to start from matematical basis of formula, to work with matlab, can anyone could help me?
