Phoretix International is British company who have been developing
electrophoresis image analysis software for PCs since 1989.
Both our 1D and 2D software packages are specifically designed for
the in depth analysis of electrophoresis gels. We can import images
in 8, 12 or 16 bit formats from many forms of image capture device,
such as commercial document scanners, CCD cameras, phosphor imagers
and laser densitometers. For visualisation purposes, the image can
then be "enhanced" using contrast stretching, false colours,
negative images or zooming in to look at a very few pixels.
However the image data itself is never altered since the software
was developed to operate within the confines of Good Laboratory
Spots or bands can be automatically detected and measured, and
quantity, MW, and many othermeasurements calculated. Histograms,
dendrograms, comparison tables and other forms of displaying the
data make the results easily assessable in a clear and instantly
I am afraid our web site is currently under construction but do
e-mail me with any questions you may have, or send me your address
so that I can forward you further information and a demo disk.
