Figure 3.

Correlation of M-ratios (top two panels) and difference of M-ratios (bottom two panels) between arrays. The mean M-ratio for each probe detected on the single-cell arrays was compared to the M-ratio for the same probe on the 5- or 10-cell array. The M-ratio is defined as log₂ (Alexa Fluor® 3/Alexa Fluor® 5).
