From: Hyperspectral microarray scanning: impact on the accuracy and reliability of gene expression data
Green contaminant presence alters resulting image from commercial scanner. Comparison of resulting images from two scanners with green contaminant present. (a) Red/Green ratio image generated from Axon 4000B microarray scanner depicting most spots as green indicating the control gene was expressed to larger extent than the treatment. (b) Cy5/Cy3 ratio image generated from HSS concentration maps depicting only a few spots as differentially expressed.
