Autoantibody Profiling Service for IgA and IgE

IgA and IgE are important autoantibody subtypes for many autoimmune, infection and allergic diseases. With our high-thourghput autoantigen microarray platform, we are able to detect autoreactive IgA and IgE autoantibodies to a broad range of autoantigens with high sensitivity and specificity. With this service, we can simultaneously detect autoreactive IgA and IgE autoantibodies against up to 125 antigens on each array. Minimum 10ul of serum is required for each sample and each chip can process up to 15 samples. The samples will be treated with DNAse I, diluted 1:50, and incubated with autoantigen array. The autoantibodies binding to the antigens on the array will be assayed with Biotinylated and IgA and IgE secondary antibody and then detected with fluorescent labeled anti-biotin for imaging. The arrays will be scanned with GenePix® 4400A Microarray Scanner and images will be analyzed using GenePix 7.0 software to generate GPR files. The averaged net fluorescent intensity (NFI) of each autoantigen will be normalized to internal controls (IgA or IgE). The final data output will be Excel spreadsheet containing both non-normalized and normalized signal intensity as well as the Signal to Noise Ratio (SNR) for all antigens. The total turnaround time for sample processing will be around 2 weeks.
$75 per sample (chip not included), maximum 15 samples per chip.
