Single click automatic scoring

Live video technology

Comet Assay IV has the ability to score comets from a live video. This makes Comet Assay IV the fastest, easiest and most accurate way to score comets to date.

Comet Assay IV is supplied with a USB video camera delivering up to 3x the resolution of previous models. This makes it possible to use lower power microscope objectives, offering a larger field of view and greater depth of field.

This combination greatly improves scoring speed, with more comets per field and less time spent at the controls of the microscope.

Unrivalled productivity and reproducibility

Comet Assay IV introduces Click&Score - a revolutionary automatic scoring method in which a single click on a comet initiates & completes the entire measurement cycle, including background correction, determination of head and tail regions and computation of all parameters.

With Click&Score, you simply have to identify the comet to be scored with a single click of the mouse. This has productivity and reproducibility advantages over manual framing methods that require users to position a measurement frame around each individual cell.

Eliminate user subjectivity and bias

The Click&Score method does not require the configuration of any adjustable settings, thereby eliminating all subjectivity from the scoring process.

Click&Score automatically compensates for slides with uneven backgrounds or varying levels of brightness, ensuring comparable results across a wide range of slides; even highly damaged 'hedgehog' comets can be accurately and consistently measured.

In addition, to further remove user bias, measurements for each slide are viewable within a scrollable results window, which can be hidden entirely for those wishing to score blind.

Data security ensured during scoring

Once the desired number of cells has been scored with Comet Assay IV, the user is prompted to save the data to Microsoft Excel before moving on to score the next slide.

For additional security and GLP compliance, the system can be configured to send result data to an Oracle database.

Quotes

Yes, it is very useful and we are in the process of writing a paper also from the data derived from Comet Assay IV.

Staff Chemist, Marine Laboratory, USA

...and the system is running great.

Medical Researcher, Cancer Research Institute, USA

Comet Assay IV software is in use. Currently our comet analysis is based on tail moment measurement and I must say that everything works properly.

Researcher, Cancer Research Institute, Slovakia

So far, I'm very happy with the system.

Research Lecturer, University, UK

Perfect and very clear installation and training!

Researcher, Contract Testing Laboratory, Europe

We have just recently utilized the system and are extremely pleased.

Assistant Professor, University, USA

We are really very happy with the comet analysis system.

Research Scientist, University, Austria

Excellent, perfectly straightforward.

The system is up and running. Everybody is impressed with the speed of scoring slides.

Researcher, University, South Africa

Total change in our lab since you came (with Comet Assay IV of course...)! thanks... :-)

Postgraduate Researcher, University, France

We are very satisfied with your software.

Scientist, Cancer Research Institute, Slovakia

It is, indeed, much quicker than the old image analysis system that we had. We are very pleased with it.

Senior Researcher, Public Health Agency, Finland

We are very happy with everything, it is easy to work with your software.

Senior Scientist, National Health Institute, Portugal

The system is working great.

Senior Research Scientist, Cancer Research Institute, UK

We started using Comet Assay IV and it works well...

Researcher, Nuclear Agency, France

The installation was quick and all the details were described and easily understandable for the technicians.

Head of Department, Global Chemical Company, Germany

Thanks for your attention and great service. I am so glad that we have Comet IV.

Study Director, Contract Research Organisation, USA

I have been using the Comet Assay IV Software. It is great! During my software validation, I realized how much easier and precise it is compared to our old software. It makes analyzing the comet slides more enjoyable

Scientist, Medical Research Centre, USA

I don't have any questions about the software as it has worked quite well for us...so far we are very happy with the software.

Research Scientist, University, Australia

I'm really a fan of your system :)

Genetic Toxicologist, Global Pharmaceutical Company

We're now using the software and it works great. It has cut our time for comets by at least half.

Post Doctoral Fellow, National Institute of Health, USA

We have found the Comet Assay IV software very useful and convenient.

Everything has gone very well with the system and we are very pleased with it.

Scientist, University, UK

It is actually working great.

Professor, University, USA

Just to let you know we have started the validation study for Comet Assay IV and it has been going very well! We ran a comet assay last week and scored the slides with no problems at all. I am very pleased with the system and it will certainly make a difference when we run some comet studies this year!

Study Director, Food & Household Products Company, UK

We have had no problems so far, and we are very pleased with the system.
