Cambridge, UK, 5th July 2019: TTP Labtech Ltd., a global leader in the design and development of automated instrumentation and consumables for life science applications, has today announced the introduction of chameleon, an industry-enabling sample-preparation system for cryo-electron microscopy (cryo-EM). The new system has been designed to enable consistent application of samples to high-quality foil grids for cryo-EM analysis, automating the current standard approach, which is a technically-demanding, largely manual process.

Based on the academically developed Spotition instrument conceived at the New York Structural Biology Center, chameleon represents the next generation of sample-preparation solutions for cryo-EM. This will allow researchers in this rapidly growing field to more easily and accurately determine the structure of biomolecules, to support protein research and drug discovery.

Relatively recent advances in resolution have meant that cryo-EM is able to effectively solve protein structures that were not previously possible using traditional methods like NMR and X-ray crystallography. However, the challenging process of obtaining vitrified samples of suitable thickness on foil grids presents a significant bottleneck. The chameleon instrument developed by TTP Labtech allows researchers to automate this process in a reliable and consistent manner – enabling scientists to overcome some of the key limitations that have held back cryo-EM from reaching its full potential.

The new chameleon automation will bring significant improvements to current sample-prep workflows, including:

  • High speed blot-free plunging
  • Automated grid handling
  • Grid screening based on ice thickness

Integral to chameleon is an algorithm that calculates the optimal plunge time for freezing, to protect and conserve samples for improved 3D imaging.

David Newble, Managing Director of TTP Labtech said, “We are extremely excited to be launching the chameleon system, which enables high quality, repeatable preparation of samples for cryo-electron microscopy. This technology will enable scientists to improve data quality and significantly reduce the time required to prepare protein samples for imaging”.

In support of this continued focus on cryo-EM TTP Labtech is also announcing the acquisition of Quantifoil Micro Tools GmbH (“Quantifoil”) into the group, creating a mutually beneficial partnership, bringing a wealth of expertise in the manufacture of speciality support foils for electron microscopy applications to TTP Labtech. Quantifoil will benefit from additional resources to support its future growth through technology development, expansion of production capabilities, and an increased global market reach.

Kay Pfennighaus, Quantifoil Managing Director said, “We're looking forward to aligning with TTP Labtech, and believe this partnership will provide Quantifoil with many valuable resources as we continue to grow and develop the business globally. We see many synergies in this partnership and are looking forward to the future.”
