Review date: 23 Oct 2014

Application Area: Crystallography optimization
dragonfly®

"I used the product to set up two optimization plates. Each one had a different buffer with pH gradient across one direction and increased concentration of PEG across the other. One of the plates had to be split into two areas, one with a constant amount of salt and the other without. Designing the plates with the designer software was easy and straight forward, and setting up the plates was quick and easy. The help I received from TTP Labtech was very useful to get my head around the designing and set-up steps. Two issues I would like to mention, it would be great if there is a way to set-up a pH gradient accurately rather than mixing from two pH values. It will also be helpful if the designed plated can be forwarded directly to the set-up software. All the best. "

Manufacturer's Response

Thank you very much for your review! We would like to mention that we are in the process of adding pH-gradients. We will keep you updated!

"The user interface is very "user friendly" and very flexible. The Dragonfly works fast and so far, the accuracy of the dispensing is very satisfying, even with small volumes (30 ul final volume). The support team is very helpful and prompt to answer. Fantastic product. "

Review date: 31 Aug 2014

Application Area: Liquid-handling
dragonfly®

"The dragonfly® could be seen as an evolution of the successful technology Mosquito®. The volumes handled are simply larger (microliters). The new robot uses positive-displacement and disposable syringes for pipetting. This enables the accurate handling of viscous solutions such as glycerol at a relatively high speed. As for the Mosquito®, the robot has a small footprint and the interface is user-friendly. Finally, the robot is very robust. We have been using the first of its kind intensively for preparing crystallization screens in 48- and 96-well plates for more than a year without a glitch. In any case, TTP Labtech offers an excellent support. We are now starting to develop other applications such as high-throughput PCR in 384-well plates. "

Description

 

dragonfly®

dragonfly enhances protein crystal screen optimisation. dragonfly is the ideal system to complement TTP Labtech’s mosquito® in the protein crystallisation workflow. Once the initial crystal ‘hits’ are identified, dragonfly produces a set of optimised conditions to grow better diffracting crystals.

dragonfly combines non-contact, positive displacement pipetting with disposable tips (ensuring zero cross-contamination) to automate the screen optimisation process. Each pipette can dispense any volume (within range of 0.5 – 4 µL) of any liquid into any well of the plate, allowing complex assay gradients or optimisation screens to be prepared in under 5 minutes.

Benefits of dragonfly include:

  • no liquid classification – making set-up quick and easy
  • flexible automation – dispense any volume from 0.5 µL upwards, into any well, from any syringe. Independent control of each channel
  • accuracy and precision – accurate and precise dispensing of all types of liquids regardless of viscosity
  • negligible evaporation of the dispensed reagents due to minimal set-up time
  • fast – rapid completion of plate irrespective of viscosity variation in stocks (5-8 mins)
    • pour and GO – simply decant the stock volumes you need directly into the reservoirs from any bottle or tube – minimum preparation time
  • stock integrity – positive displacement technology preserves stock integrity, even for volatiles
  • optimal sample use – low dead volumes < 0.5 mL that are recoverable if required, combined with extremely accurate dispensing mean that precious samples go further and allowing more extensive screening
  • zero cross contamination – use of disposable mosquito tips and non-contact dispensing guarantees zero cross-contamination
  • ease of use – software is extremely simple to use, design and dispense
  • robust – focused and uncomplicated workflow avoids physical user errors, low maintenance (no chance of blocking or clogging)
  • screen designer software – interactive, powerful and simple tool to make set-up easier

These features allow the easy creation of even complex gradient plates.
Key application areas include:
  • screen optimisation set-ups for protein crystallography
  • biological assay development
  • formulation development
