Brain and Neuronal-associated Antigen Array

GeneCopoeia’s OmicsArray™ Brain and Neuronal-associated Antigen Array is a protein microarray enabling powerful detection of autoantibodies associated with neurological diseases. The array carries 120 superior-quality purified antigens spotted onto nitrocellulose filters, which are adhered to glass slides. Antigens known to be recognized by autoantibodies in patients with central nervous system disorders are chosen based on a thorough review of peer-reviewed publications. These autoantibodies could be either causes of neurological diseases or useful biomarkers.

In addition to this premade array, arrays containing customized sets of antigens are available, as well as array profiling services and data analysis. To order premade or custom arrays, please contact us.

GeneCopoeia’s OmicsArray™ Brain and Neuronal-associated Antigen Array is part of the GeneCopoeia OmicsArray™ Antigen Microarray family.

Custom services

GeneCopoeia offers custom antigen microarray services in the following areas:

  • Custom array printing. GeneCopoeia will create custom antigen microarrays built to your specifications.
  • Sample processing. Send us your blood, plasma, tissue, or other biological sample and we will prepare it for processing and incubation with any of our premade antigen microarrays or custom-built antigen microarrays for autoantibody profiling and other applications. For information on sample types to submit, consult the FAQ
  • Data analysis. Once samples are processed and incubated with an antigen microarray, we will analyze the raw data. The standard analysis service includes: 1) An Excel file of the Net Signal Intensity (NSI) for each antigen on the array, normalized to internal controls; and 2) a heat map

Additional analysis services, including proteomic analysis, pathway analysis, and more, are also available.

Technology overview

Technology overview

GeneCopoeia's OmicsArray™ antigen microarrays contain up to 120 purified proteins spotted onto nitrocellulose filters, which are adhered to glass slides. In addition, 8 spots are included for normalization. Each slide carries 16 identical arrays, and so can be used to process up to 15 samples simultaneously as well as a negative control. As little as 1 ul serum or 50 ul of other bio fluids are needed for each sample.

As shown in Figure 1, arrays are incubated with patient samples, and any antibodies in the  samples bind to their cognate antigens on the array. The arrays are washed to remove unbound antibodies and other proteins, then co-incubated with Cy3- and Cy5-labeled secondary antibodies. The dual labeling strategy is intended to distinguish between immunoglobulin (Ig) subtypes present within samples. For example. a Cy3-labeled anti-IgG secondary antibody is used to detect IgG antibodies, and a Cy5-labeled anti-IgM secondary antibody is used to detect IgM antibodies. Fluorophore-labeled secondary antobodies are available for detecting IgA, IgD, IgE, IgG and IgM immunoglubulins, as well as IgG subclasses IgG1, IgG2, IgG3, and IgG4.

After washing to remove unbound secondary antibodies, signals are detected using a GenePix® 4400A microarray scanner. The raw data is then analyzed using GenePix® 7.0 software.
