The cost differential can be mitigated by exploiting the multiplex NimbleGen array formats, in which 3, 4, 12 or 24 samples can be hybridized to a single array.
The array format was in duplicate cores per patient.
Studying T cell activation in array format could be quite useful in identifying the roles of various T cell or antigen-presenting cell membrane proteins in this process.
Chips were hybridized at 45°C for 16 hours, washed using the FS450_0001 (49 array format) fluidics script in the Fluidics Station 450 (Affymetrix), and scanned using the GeneChip Scanner 3000450 (Affymetrix).
Tens of thousands of clones can then be screened in a colony array format using efficiency of in vivo biotinylation of a fused biotin acceptor peptide to enrich soluble clones from the library [28].
The captured glycoproteins were then probed with four different fluorescently labeled lectins in a sandwich array format, followed by characterization in situ by on-plate digestion and direct analysis using MALDI-QIT (quadrupole ion trap -TOF-MS.
Commonly used biological standards are reference RNAs that are competitively hybridized with the sample of interest in two-channel array formats, and in vitro RNA transcripts that are "spiked into" RNA samples of interest in either one-channel or two-channel array formats.
This operation was performed numerous times until the data converged, resulting in the clusters shown in Figure 2. Array Format 1 data have been deposited in the NCBI Gene Expression Omnibus (GEO) database as accession number GSE18620.
