BeadXpress Reader

System Description

The BeadXpress Reader is the optimal solution for small and high-throughput laboratories conducting molecular testing studies that benefit from robust, multiplexed-based assays. It employs a dual-color laser detection system that identifies the unique holographic codes inscribed in VeraCode microbeads and detects the signal intensity associated with each bead. This system supports the development of both single- and two-color assays.

• The BeadXpress Reader draws up to eight samples at a time from a standard 96-well plate or 8-well strip and introduces them into an eight-chambered transparent groove plate at the bottom of the system’s fluidic cell

 

• During scanning, the BeadXpress Reader compiles a virtual representation of the 96-well plate, acquires fluorescence data and associated code data for each microbead, and exports the data for downstream analysis

 

• A two-color, ten-plex VeraCode assay can be scanned at a rate of 120 samples per hour, a 96-plex assay at a rate of 80 samples per hour

Through a graphical interface, VeraScan software lets the investigator load assays, perform scans, and organize and view data. Downstream analysis is simplified through the use of Illumina’s GenomeStudio Data Analysis Software or other third-party analysis software. Because assays developed with VeraCode microbeads typically include up to 30 replicates of each bead type the data generated by the BeadXpress Reader is particularly robust.
