The Infrared Advantage

LI-COR's exclusive infrared technology provides higher dynamic range for genotyping research. A proven reputation for unparalleled accuracy and reliability results from the use of solid-state lasers and detectors.

Independent Detection

The 4300 System features a two channel detection system that uses two separate lasers and detectors to eliminate errors due to fluorescence overlap. Fluorescence of the two IRDye® infrared dyes is separated by 100 nm.

High Sensitivity and Wide Dynamic Range

Infrared detection provides a key advantage due to the high sensitivity and low background fluorescence. Infrared detection reduces the cost per genotype, since fewer reagents are required for detection.

During electrophoresis, two TIFF images are collected that accurately represent the wide range of band intensities that can be detected by the wide dynamic range of the 4300 System. True gel images promote a smooth transition from manual methods.
