This document is an operation manual for the HP GeneArray scanner.
The Hewlett-Packard (HP) G2500A GeneArray Scanner is a bench-top laser-based instrument designed to read Affymetrix GeneChip probe arrays. It measures the intensity of fluorescence from labeled sample nucleic acids bound to the arrays, utilizing a focused laser spot size of less than 4 microns.
| Laser spot size | less than 4 microns |
|---|---|
| Probe cell minimum size | 20 microns |
A large format (1.28 cm X 1.28 cm) GeneChip probe array can be scanned in about five minutes for a single scan with a single dye.
Technical support is coordinated by Affymetrix as a component of the GeneChip system.
