Overview of Quantity One
Quantity One is a powerful, flexible software package for imaging and analyzing 1-D
electrophoresis gels, dot blots, arrays, and colonies.
The software is supported on Windows and Macintosh operating systems and has a
graphical interface with standard pull-down menus, toolbars, and keyboard
commands.
Quantity One can image and analyze a wide variety of biological data, including
radioactive, chemiluminescent, fluorescent, and color-stained samples acquired from
densitometers, phosphor imagers, fluorescent imagers, and gel documentation
systems.
An image of a sample is captured using the controls in the imaging device window
and displayed on your computer monitor. Image processing and analysis operations
are performed using commands from the menus and toolbars.
Images can be magnified, annotated, rotated, and resized. They can be printed using
standard and video printers.
All data in the image can be quickly and accurately quantitated using the Volume
tools.
The lane-based functions can be used to determine molecular weights, isoelectric
points, VNTRs, presence/absence and up/down regulation of bands, and other values.
The software can measure total and average quantities, determine relative and actual
amounts of protein, and count colonies in a Petri dish.
The software can cope with distortions in the shape of lanes and bands. Lanes can be
adjusted along their lengths to compensate for any curvature or smiling of gels.
Image files can be shared among all The Discovery Series™ software. Images can
also be easily converted into TIFF format for compatibility with other Macintosh and
Windows applications.
