Comprehensive measurements and results

Easily graph and report your data

Comet Assay IV combines accurate, repeatable results with powerful data processing and comprehensive presentation. Once you have obtained your results, you can easily process them using the Spreadsheet Generator, which is included free with every Comet Assay IV system.

The Spreadsheet Generator is an application built in Excel for drawing graphs, tabulating data and calculating statistics from your Comet Assay IV results. Because it is built in Excel, it can easily be customised using any of Excel’s standard functions and features.

Includes all major measurement parameters

Comet Assay IV incorporates all major measurement parameters, including Olive tail moment and tail % DNA - widely regarded as the most informative measures of DNA damage in the comet assay.

With Comet Assay IV you can report the following:

  • Olive tail moment
  • Head % DNA
  • Tail % DNA
  • Head length
  • Tail length
  • Tail migration
  • Mean grey level
  • Total area
  • Total intensity
  • Width

The Spreadsheet Generator: Powerful data processing

All the comet assay results files produced by the Comet Assay IV system can be used with the Excel-based Spreadsheet Generator, which is supplied free with every Comet Assay IV system.

The Spreadsheet Generator is provided to help generate graphs and tables in Excel from the raw data produced by the Comet Assay IV program. The Spreadsheet Generator will extract data from any number of source files you specify, create tables and draw charts.

Full customisation of the Spreadsheet Generator is possible, therefore the program can be used in compliance with the reporting system in your laboratory.

Spreadsheet Generator features:

  • Create tables to compare data sets
  • Draw charts bespoke to your project’s needs
  • Amalgamate data from different experiments, studies or days, should you wish
  • Produce graphs including log transforms and frequency distribution graphs
  • Generate summary statistics over any set of result files you choose
  • Merge files for example, where there are several slides of the same dose and treatment
  • Compare data across dose ranges
  • Choose from a selection of BoxPlot and Histogram options
  • Flexibility to adjust chart layouts and use them in other applications (e.g. copy and paste into reports, or automatically integrate using OLE)
  • Customise your Spreadsheet Generator to include additional calculations and Excel charts (e.g. line and bar charts)

I'm really a fan of your system :)

Genetic Toxicologist, Global Pharmaceutical Company

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

Research Scientist, Food Safety Agency, France

We are impressed indeed! It has saved us quite a lot of time and pains.

Director, Toxicology Research Centre, Spain

We have installed the software and are using it without any problem. It's really simple! My PhD students are very happy with it.

Professor, University, Spain

All is going well and the more I use the software the more I love the way it's so simple and intuitive...the comet software is running well and in increasing use.

Scientist, University, UK

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

Senior Researcher, Public Health Agency, Finland

The system is working great.

Senior Research Scientist, Cancer Research Institute, UK

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

Head of Department, Global Chemical Company, Germany

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

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

Researcher, University, South Africa

It is actually working great.

Professor, University, USA

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

Researcher, Nuclear Agency, France

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

Study Director, Contract Research Organisation, USA

We are using the Comet Assay IV a lot (and our use is increasing). It's working very well.

Professor, Children's Research Hospital, 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

The current Comet Assay IV system works without any trouble…we are pleased with the system.

Scientist, Chemical Company, Japan

Perfect and very clear installation and training.

Study Director, Contract Research Organisation, Europe

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

Postgraduate Researcher, University, France

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

...we are "happy users" of the software

Senior Researcher, Risk Assessment Institute, Germany

Perfect and very clear installation and training!

Researcher, Contract Testing Laboratory, Europe

...Everything is fine with the Comet Assay IV system...and I'm pretty happy about this new software with just clicking on the cells instead of drawing a frame around them

Researcher, Cancer Research Organisation, UK

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

Professor, University, UK

It's an amazing program! Really useful!

Research Scientist, University, Brazil

...and the system is running great.

Medical Researcher, Cancer Research Institute, USA

I love the software. Keep up the good work over there.

Study Director, Contract Research Organisation, USA

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 are very satisfied with your software.

Scientist, Cancer Research Institute, Slovakia

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

Assistant Professor, University, USA

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

Research Scientist, University, Australia

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

Senior Scientist, National Health Institute, Portugal

The Comet Assay IV system we already installed and is working perfectly.

Scientist, Environmental Institute, Norway

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

The system was set up last month, and so far it works very well. Both my boss and I are very satisfied with it and like it very much.

Researcher, University Hospital, Germany

So it's working out fine and we're very happy!

Toxicologist, Health Agency, Canada

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

Research Lecturer, University, UK
