Application Overview

ELISA detection can be converted to near-infrared FLISA detection on the Odyssey System.

• Involves substitution of IRDye 800CW^® Streptavidin for the horseradish peroxidase conjugate

• Eliminates the enzymatic reaction and the need to time and stop the colorimetic reaction

• Allows dry assay plates to be stored in the dark and imaged at convenience

• Completed easily in 2.5 hours
