Defined 200-400 bp fragments of selected cDNAs were generated by RT-PCR, cloned and sequence-verified. Amplified and purified cDNA inserts were spotted in quadruplicate on PIQOR slides using a proprietary piezoelectric spotter. The PIQOR slides were coated in a 2 step process generating a surface which covalently binds DNA molecules.
Description
The PIQOR Immunology Microarray is composed of 1076 mouse specific cDNAs. These cDNAs include for each array six house-keeping genes as positive controls. In addition four E. coli DNA fragments and the corresponding in vitro transcribed RNAs (spiking controls) provide a control for the labeling and hybridisation efficiency. Two negative controls are given by spotted herring sperm DNA and buffer. Genes are spotted in quadruplicates.
