From: Improving signal intensities for genes with low-expression on oligonucleotide microarrays
(A) For selected low-expressing genes (HK3, HK8, HK9, HK10, HK13, HK15, HK17, HK 20 and R9), plots of the relative increase in signal intensity of the 20, 30, 40 and 50 μM probe concentration in comparison with the 20 μM nucleotide probe. The y-axis is the relative increase in signal intensity and the x-axis is the concentration of the probes. (B) Corresponding plots for the eight high-expressing genes (Co1, Co2, Co3, HK2, HK3, HK4, HK5 and HK12).
