GeneCopoeia OmicsArray antigen microarrays

Click2Contact

GeneCopoeia’s OmicsArray antigen microarrays are protein microarrays engineered for several powerful applications, including autoantibody detection, biomarker profiling and characterisation of protein–molecule interactions. Antigen microarrays enable parallel detection of antibodies or other biomarkers present in patient samples for diseases including rheumatoid arthritis, muscular dystrophy, systemic lupus erythematosus and type 1 diabetes.

Each array contains highly purified proteins spotted onto nitrocellulose filters, which are adhered to glass slides. Proteins known to be associated with specific diseases are chosen based on a thorough review of peer-reviewed publications. In addition to predesigned arrays, arrays containing customised sets of proteins are available, as well as array profiling services and data analysis.

The OmicsArray microarrays offer users advantages such as multiplexing allowing the capability of assaying up to 120 antigens at a time, compared with one protein at a time with ELISA. The technique is high throughput, with each slide able to process up to 15 samples in parallel.

The arrays are sensitive and are capable of detecting as little as 1 pg/mL of antibody while using only small sample volumes (1 µL of serum), a result which is 100-fold more sensitive than ELISA.
