Oligonucleotide arrays are a type of biochip, a system in which oligonucleotides of a certain length and different sequences are fixed in an orderly arrangement on a support for molecular hybridization analysis. As a highly integrated and rapid means of gene analysis, they are widely used in life science research to achieve rapid detection of genetic information in plants and animals, and greatly promote the development of plant and animal research.

CD Genomics offers excellent microarray services for a relatively wide range of different model organisms. We are committed to providing our clients with a full process oligonucleotide microarray services from experimental design, sample shipping, QC interpretation, hybridisation, scanning and data analysis. To date, we have served a large number of oligonucleotide microarray services and have many years of experience with oligonucleotide microarray. For example, we have used oligonucleotide microarray to analyse gene expression in a wide range of species under biotic and abiotic stress conditions, and to detect and identify transgenic crops. Our oligonucleotide microarray services are at the leading edge of the industry.

Characterization of oligonucleotide microarray

• Sequences are optimised to reduce non-specific hybridisation and to effectively differentiate between genes with homologous sequences.
• Reduced secondary structure.
• Uniform hybridisation temperature to improve hybridisation efficiency.
• Uniform concentration of synthesised products, avoiding differences in sample concentrations that could lead to differences in spot sizes.
• No amplification required, preventing amplification failure from affecting the experiment.
• Allows rapid screening for all possible mutations and sequence variants in genomic DNA.

Oligonucleotide microarray can be used in the following research

• Mutation detection in plants and animals
• Plant and animal sequence determination
• Gene expression analysis
• Single nucleotide polymorphism analysis
• Animal disease diagnosis
• Routine high-throughput screening
