[Preparation and analysis of oligonucleotide microarray for expression detection of mouse cytokine-associated gene].
A new method for the preparation of oligonucleotide microarray for gene expression detection was found. The key techniques and standards of quality controlling for preparation of oligonucleotide microarray was explored using gene of human 23 kD highly protein and Luciferase and mouse cytokine-associated genes. By the using of a software system MProbe, oligonucleotide probes were designed and BLAST. All the probes have a very high specificity, i.e. except target sequence, the similarity between the probe and non-target sequences is less than 70% and the hairpin structure are not exist in all probes. All the probes have the same length 40. GC contents in all probes are in a narrow scope (from 45% to 55%). All the probes are modified with amino at 5' or 3' terminal. The satisfied images with good sensitivity and very high specificity were obtained by the using of the methods above and also using of positive and negative controls and some internal controls(house keeping gene) to quantitate and balance expression of genes. High specificity, good sensitivity and stability have been verified by three continuous experiments using the oligonucleotide microarray to study gene expression profile of normal mouse breast grand tissue. The oligonucleotide microarray for expression detection prepared using our method have high specificity, good sensitivity and stability et al. It may be a more advanced method for analysis of gene expression profile.
