Complete Turnkey System
The InCyt High Speed I/PTM Imaging and Photometry System includes everything needed for calcium and other single excitation and ratiometric fluorophore experiments. The system includes: an inverted epi-fluorescence/phase contrast microscope, microphotometer assembly, low-light level integrating CCD camera, computer controlled fast changing monochromator with Xenon arc lamp, image processing computer and data acquisition/analysis software.
Ease-of-use
The InCyt High Speed I/PTM Imaging and Photometry System was designed in a biomedical research laboratory by scientists for scientists. Menu selection appears in the sequence in which experiments are performed. Esoteric options that add complexity and are rarely used have been eliminated from the menus. The software follows standard Windows graphical-user-interface-protocol. The hardware has been tested for reliability and ruggedness, as well as, simplicity of set up and operation. New users can learn to use the system and be doing their first experiment in a few hours.
Data Collection, Analysis & Presentation
Imaging data can be measured continuously on as many as 50 pre-selected regions of interest. The results can displayed in real time or images can be saved for post hoc analysis. Saved images can be played back as an animated sequence—ideal for analysis of sub-cellular responses, intercellular communication and heterogeneity among the individual cells in a population. Ion concentration within cells can be converted to color using standard or custom pseudo-color tables. Image sequences can be presented as a montage with user-defined annotation for presentation and publication. Data generated by InCyt High Speed I/PTM are stored in a standard TIFF format and data files are stored as ASCII text.
