The RAMP Reader

Immunoassays based on fluorescence have substantially greater sensitivity and dynamic range than those based on earlier-generation detection techniques.
 
Nevertheless, the development of such assays has been limited by the need for stable dyes that do not cause sample interference, and the fact that the instrumentation required was both complex and expensive.
 
The RAMP^® technology overcomes these limitations by using proprietary dyes that are both stable and free of interference. The Reader incorporates a single detector tuned to the emission wavelength of dye used to label the latex particles. When the chemical reaction in the Test Cartridge is complete, the analyzer emits excitation light, causing the dye to fluoresce at a wavelength that can be detected by the analyzer.
 
The RAMP System uses proprietary software on programmable, read-only lot cards, which are inserted into each analyzer when a new lot of tests are purchased.
 
These chips enable the Reader to perform multiple types of assays and automatically determine which test is being run. The chips are designed to automatically calibrate the Reader on a lot-specific basis.
