1)Contact-free cell deformation
Contact-free cell deformation” open=”0″ style=”2″]Suspended cells are deformed by optical forces, leading to absolutely contact-free measurements. This ensures homogeneous cell handling and avoids artefacts due to contact-induced cellular reactions.
2)Timesaving, automated measurements
Cells are automatically delivered to the measurement region and deformed corresponding to the user-defined stretch pattern. While the Optical Stretcher runs the experiment you can focus on interpreting results.
3)High-throughput single cell rheology
By integration of a microfluidic system about 300 cells/hour can be measured with ease. This allows for the first time to collect significant statistical data from cell rheology.
4)Better statistics compared to AFM
A cell is trapped by two opposing laser beams, which hold it and pull on both sides of it. Higher laser powers are used to deform the cell. The cell deformations are recorded by a CCD camera and evaluated by a custom designed software. The measurement chamber of the Optical Stretcher is integrated into a microfluidic system, such that cells can be easily delivered one after the other. High throughput rates of about 250 cells per hour can be achieved, allowing for better statistics compared to other tools such as atomic force microscopy (AFM).
PicoTwist is involved in nanomanipulation and single-molecule experiments in biology. Historically, single molecule experiments were among the first nanotechnologies, appearing in the 1990s to characterize biopolymers and proteins with unprecedented accuracy. The idea is that instead of analyzing the behavior of a great number of molecules as usually done in a test tube, you now analyze the behavior of a single molecule. Thus instead of measuring average behavior you have direct access to the biopolymer’s activity in real time.
The Atomic-Force-Spectrometer (AFS) is an instrument for the study of single proteins placed under a calibrated mechanical load. The AFS is used to understand how mechanical forces, over the full biological spectrum, affect the dynamics and chemistry of proteins. The AFS allows for the picking-up and mechanical manipulation of single recombinant proteins. The AFS instrument was designed to be fully automatic and be able to operate for days, unattended by an operator. Its operating software includes routines that unambiguously identify the mechanical fingerprints of the protein being studied, and thus is able to recognize and store data automatically. At the end of a daylong experiment, it is possible to collect several hundred single-protein traces.
This Set-up was specially developed for the demands of microinjection. With this design we have put a high value on ergonomy, individualization and comfortable operation. All functions have been built the respective Trackball-Keypad with this Set-up, so that a genuine one-hand-operationality exists. The fact should be highlighted that the operation of the manipulator in three dimensions as well as the control of the dosing units (injection, aspiration and holding) is maintained through the Trackball and both function keys. Thereby the operators hand does not need to be raised from the keypad throughout the injection, so that full concentration can be given to the carrying out of the injection.Many other helpful functions enormously assist and speed up the work-process, which is specially noticeable in routine work. Through is high levbel of flexibility this Set-up can be combined or re-arranged at will, and fulfills the most differing expectations. The field of application ranges from ICSI to Transfer to the injection of color-dyes.

UnipicK is a vacuum-assisted single cell collection and tissue microdissection instrument based on NeuroInDx’s original capillary-based cell and tissue acquisition system (CTAS; USPT 8,797,644; Kudo et al, 2012) that can acquire individual cells from cell cultures and tissues. It permits rapid acquisition of single cells from any untreated cell cultures, providing reliable and affordable means of most sophisticated experimentation. Moreover, the instrument is suitable for individual cell collection and region specific acquisition of subanatomical areas from complex heterogeneous tissues such as the brain. Operation of the system is intuitive and requires minimal training. Cell cultures require no treatment or specific peripherals, thus enabling unmatched flexibility in experimental design and sample collection.
Perhaps one of the most distinct features is the ability of UnipicK™ to collect live cells for further reculturing and a plethora of downstream functional studies. Both individual fluorescently labeled and morphologically distinct cells can be acquired from any cell cultures or tissue sections. The procedure has been demonstrated from nearly all types of adherent, suspended and 3D cultures, including difficult samples such as primary cells, or individual cells from fresh frozen and sucrose treated complex tissues, such as brain (please, see http://www.youtube.com/user/NDXInc). With live cells viability tests have demonstrated up to 99% after collection, and up to 30 cells per minute may be collected from adherent cultures.
Notable Features of UnipicK™ include:
– Simple operation with minimal training
– Single cell collection from untreated cultures and tissue sections
– Efficient tissue microdissection
– High viability of collected cells
– High quality RNA and protein for downstream – omics studies
– Flexibility and versatility – fit any inverted microscope
– Fraction of the cost of any laser assisted microdissection instrument
UnipicK+ is a universal platform for tissue microdissection, single cell acquisition, and deposition into the single wells for further molecular analysis or clonal expansion.

Developed system can microdissect tissue sections, collect and deposit individual cells from any adherent cultures grown in standard cell culture dishes in as small as 15 nl volume, compatible with various downstream single cell analyses and next generation sequencing. Like UnipicK, the system may be used with a wide range of inverted microscopes. The benefits include cost-efficiency, simple operation, digital interface, complete workflow from single cell isolation to downstream analysis, compatibility with a wide range of inverted microscopes and use of standard plates and culture dishes.
