Composite images of ADGE microarray and regular microarray. The clones corresponding to the contiguous area of twelve spots (3 × 4) were amplified by using PCR with the primers having a Taq I site at the end. After cut with Taq I , the same amount of DNA for each clone was ligated to the CT and TT adapters. The CT and TT adapter-linked DNA fragments were mixed in ratios of 1:1 for the three clones of the first column, 1:2 for the clones of the second column, 1:3 for the clones of the third column, 1:4 for the clones of the fourth column. The top panel is the result of ADGE microarray while the bottom panel is the result of regular microarray. The ratios are represented by Cy5 (green) to Cy3 (red) and normalized with the value of clones in the first column. The detected ratios are averages of three spots in each column.

Illustration of the microarray experiment. The various steps of the experiment and the corresponding covariates used in the model are listed with their symbols. The model consists of three levels: (i) selection, (ii) scanning and (iii) measurement. In (i), K g 1 and K g 2 mRNA molecules for gene g present in sample 1 and 2 undergo a selection process. Each molecule succeeds or fails in each of the experimental steps: cDNA synthesis, dye labelling, purification, hybridization and washing. Success for each molecule is modelled as a Bernoulli coin toss. The success probability depends on properties of the molecule and of the experiment (covariates). Molecules of the same gene can have different covariates, e.g. if they hybridize on different spots with different probes. If probe is in excess, molecules can be modelled as independent variables and the number of remaining molecules after each step is binomially distributed. The probability of successfully passing through the entire experiment is the product of the probabilities of surviving each individual step. Nested binomial variables are binomial and the final number of molecules ready for being scanned is binomial with two parameters: the unknown original number of transcripts per gene in each sample and the selection probability, modelled as in . Level (ii) describes the translation of the bound molecules remaining after washing ( H s t , a , on array a , spot s , for sample t = 1, 2) into fluorescence intensities, as in . Measurement error (iii) of pixel-wise intensities L j , s t , a (on array a , pixel j on spot s for sample t = 1, 2) is assumed to be normally distributed as in . This model allows to obtain estimates of absolute concentrations K g 1 and K g 2 together with their posterior marginal probability density, as sketched at the bottom.
