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 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

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

We are really very happy with the comet analysis system.

Research Scientist, University, Austria

Perfect and very clear installation and training.

Study Director, Contract Research Organisation, Europe

...have been using it now for a couple of weeks and it seems to be working great. Very user friendly - I love it as does my intern!

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

Assistant Professor, University, USA

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

Senior Researcher, Risk Assessment Institute, Germany

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

It's an amazing program! Really useful!

Research Scientist, University, Brazil

...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

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

Researcher, University, South Africa
