What's new?

ProRT Reverse Transcriptase

ProRT is genetically optimized thermostable enzyme ideal for cDNA synthesis and one-step amplification techniques, such as RT-LAMP and RT-qPCR.

Taq DNA Ligase

Thermostable DNA Ligase for advanced techniques such as, Gibson assembly, Ligase chain reaction (LCR), NGS, inverted repeat amplification and gene synthesis from Thermus aquaticus.

TEV protease His6

We offer genetically enhanced form of TEV protease with higher activity and thermal stability. This in house developed enzyme shows a superior activity/costs ratio. Available also in bulk quantities upon request.
