Diffinity Genomics has launched the Diffinity RapidTip2 for PCR purification and polymerase removal prior to cloning or Sanger sequencing.
RapidTip2 enables PCR purification in one minute with a single mixing step using only a standard pipettor, with no additional reagents, consumables, or equipment. The technology comes prepackaged in a single pipette tip. Unincorporated dNTPs, primers, primer-dimers, and DNA polymerase are removed by aspirating the PCR sample into the tip; and the purified PCR product can be dispensed from the tip and used immediately in downstream applications.
RapidTip2 comes in two formats for compatibility with either universal or Rainin LTS-style pipettes, and is optimized to purify a 50 µL sample volume.
Bibby Scientific has introduced redesigned versions of its Techne Prime range of thermal cyclers.
The new thermal cyclers — the 3Prime, 3PrimeX, 3PrimeG, Prime, and PrimeG — all feature easier programming and increased flexibility compared to previous models, the company said. All models have an enhanced thermal engine, a color touch interface, and pre-programmed protocol templates.
3Prime is an entry-level thermal cycler that can store up to 1,000 programs and features rapid ramp rates and a small footprint. Bibby said that it is ideal for research and teaching labs.
3PrimeX and 3PrimeG are mid-sized cyclers that offer expanded sample capacity and gradient cycling capability.
The Prime and PrimeG are full-sized models with an interchangeable block system ideal for all routine PCR experiments, Bibby said.
