Enzymes
Ready-to-use PCR and high-fidelity PCR enzymes and DNA polymerases have been developed for fast PCR and are designed for superior sensitivity and yield. A combination of the latest advances in buffer chemistry and PCR enhancers, in conjunction with an antibody, aptamer, or chemical-mediated polymerases and DNA polymerases, promotes rapid, consistently accurate detection of DNA and cDNA targets. Glycerol-free options allow room temperature shipping and storage, extended shelf-life, and increased flexibility in sample volume, and isothermal options are available for loop-mediated isothermal amplification (LAMP).
