Biomarker discovery and quantification

Biomarker discovery and quantification

Biomarkers can act as predictive, diagnostic or prognostic indicators of disease state, or as indicators to how an individual is responding to medical treatment. Microarray provides a cost-effective, versatile and robust platform for high-throughput, multiplex screening of large patient cohorts. Purified proteins are spotted and immobilised on a solid structure, such as a slide or microplate, then interrogated using patient or control samples to determine the presence of relevant biomarkers.

"CDI Laboratories recently purchased an Arrayjet ‘Ultra Marathon II’ to print microarrays for our ‘HuProt’ product line, focussed arrays with a smaller subset of proteins for discovery arrays and hybridoma project work. CDI is planning to print monoclonal arrays and membrane protein arrays with the new technology in the near future. Arrayjet’s technology was chosen as we needed to quintuple capacity, preferably with one Instrument, its hi-tech, precise and user-friendly capabilities were an obvious benefit. One of the added advantages of the company structure is that they provide in-house printing through ‘Arrayjet Advance’ and we were able to carry out several studies over several months to reaffirm our belief that the technology would improve many facets of our operation."
