(1st Feb '12)Comet Assay IV: data processing is easy.

The Spreadsheet Generator is an Excel-based program which allows you to easily generate graphs and tables 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.

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

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

 ”I couldn’t imagine processing our comet data without the Spread Sheet Generator”
- CRO Scientist, UK.

“Wow, is this really free?”
- Group Leader, Germany.


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 (i.e. copy and paste into reports and presentations)
Customise your Spreadsheet Generator to include additional calculations and Excel charts (e.g. line and bar charts)

(22nd Dec '11)Sorcerer Colony Counter in spearmint tea investigation

Spearmint (Mentha spicata) has long been considered beneficial to health. To study the anti-genotoxic effects of spearmint, the Ames test has been used.

The method involves administering two compounds simultaneously to the Salmonella strains involved within this well-known assay. The histidine-positive revertant colonies were then counted using a Sorcerer Colony Counter.

When combined with additional results, the findings of this study suggest that spearmint tea protects against the mutagenic activity of IQ (2-amino-3-methyl-3H-imidazo[4,5-f]quinolone) through the inhibition of carcinogen activation and via direct effects on the activated metabolite(s).

(14th Nov '11)Where will GeneTox testing be in 30 years time?

Earlier this month, Perceptive Instruments attended the one-day event hosted by the Industrial Genotoxicology Group (IGG, a UKEMS interest group) entitled: “Where will Genetic Toxicology testing be in 30 years time?” The event was held at the Royal Society of Medicine, London, and speakers came from across the globe to share their thoughts and ideas on the future of GeneTox testing.  

The intention of this year’s meeting was to highlight areas of current, on-going research that promise to advance or re-shape this field over the next decade. There was particular focus on Structure Activity Relationships (SAR) and other in silico prediction tools.  The definite consensus of the delegates in attendance was that computer models to predict toxicity and efficient data sharing between groups are necessary developments for the future of GeneTox testing.  The idea of using new stem-cell technology for drug discovery and toxicology was explored and there was a gripping presentation on epigenetics, one of the fastest moving fields in drug discovery.  In addition, there was a presentation from the EPA defining the future of risk assessment and the use of emerging molecular and systems biology knowledge therein.  

So, where will genetic toxicology be in 30 years time?  The short answer is that no-one can be certain.  We can be confident, that the Ames Test will remain a firm feature in the genetic toxicology testing suite and due to the rigorous legislation process involved with GeneTox testing, there will be adequate notice before any new assays are introduced.  However, to speculate and to understand the recent advances and developments is interesting and will no doubt help the future of toxicology testing in the 21st century and beyond.  


(28th Sep '11)New Sorcerer Colony Counter released

Sorcerer Colony Counter Perceptive Instruments is proud to announce the release of Sorcerer 3. The latest version includes a range of important enhancements and new features, making Sorcerer 3 one of the most powerful and flexible image analysis systems on the market.

Sorcerer now comes as standard with a new high resolution FireWire camera capable of detecting and measuring colonies with diameters as small as 80 microns. The new camera allows more accurate shape discrimination and object separation while retaining the live video display that allows rapid throughput of samples.

The system has been developed with reference to a wide range of regulatory guidelines and is designed to be fully compliant with Good Laboratory Practice (GLP) standards as set down by the OECD.

Sorcerer has long been established as the system of choice for many laboratories and contract research organisations that need to comply with the FDA 21 CFR part 11 regulations on electronic signatures. The new, enhanced Sorcerer 3 system boasts increased database security and heightened flexibility in data entry configuration. Users can be prompted to justify all auditable actions in a customised manner, resulting in a robust, but adaptable, approach to achieving compliance.

With Sorcerer 3's enhanced image processing functions, users can build a sequence of powerful image processing functions to extract the measurement information needed for a specific application. The system configuration can be saved so that Sorcerer can tackle a range of different applications by simply recalling the appropriate configuration.

Custom measurement frames can now be saved for reuse - this is useful for situations in which a certain area, such as a moulding mark on a Petri-dish, needs to be excluded in multiple measurements.


(26th Sep '11)Visit us at the EMS 42nd Annual Meeting and International Conference on Occupational and Environmental Health

Perceptive Instruments is sponsoring and exhibiting at both the Environmental Mutagen Society (EMS) 42nd Annual Meeting and the International Conference on Occupational and Environmental Health (ICOEH) in October 2011.
