GRiSP presents a full range of DNA polymerases and mastermixes with specific characteristics, designed to perform with excellent results for your most demanding applications. In comparison with GRS Taq, the Xpert product range allows for an improved performance to overcome specific needs. Xpert Taq is intended for routine PCR with increased yield, whereas Xpert Fast allows for ultrafast cycling. If specificity is an issue, we recommend Xpert Hotstart, as in the case of demanding samples and/or long PCR. For low-error rate or blunt-end cloning, Xpert HighFidelity is the enzyme of choice.
