Allergen Protein Arrays


The RayBio® Allergen Protein Arrays are semi-quantitative multiplex protein immunoassays developed for the detection of common allergens. Recombinant allergen proteins or extracted native allergen proteins are spotted onto a solid glass slide surface, and then probed for the presence of serum specific antibodies to these allergen targets. These detection kits can then be applied in screening specific allergens based on IgE and/or IgG levels present in patient serum samples.

Allergen Protein Array Features

Multichannel PipetteGet 3x the data, plus high throughput

Each 75mm x 25mm glass slide is spotted with either 4 or 16 identical protein arrays (also called  “subarrays”). Within each subarray, the allergens along with controls are spotted in triplicate. The slide comes with a 16-well removable gasket and chamber assembly that allows for simultaneous processing of up to 16 samples per slide (4 if using the 4 sample kit). To achieve even higher throughput, 4 slides can be nested into a tray which matches a standard microplate, allowing for automated processing of 64 arrays (If using the 16 sample kit) simultaneously. The latest automated liquid handling work stations can accommodate several trays at once, allowing hundreds of samples to be processed per day.

How It Works

Allergen Protein Array - How it works


A panel of allergen proteins is printed in multiple identical arrays on a standard slide. After a blocking step, samples are incubated with the arrays. Nonspecific antibodies are then washed off, and the arrays are incubated with Biotin-conjugated anti-human IgG and/or IgE detection antibodies, followed by a streptavidin-conjugated fluor. Signals are then visualized using a fluorescence laser scanner.
