RayBio® Cytokine Antibody Array simplifies the detection of cytokine expression from biological samples. Our array-based technology is the first product available to simultaneously detect multiple cytokine expression in an array format. By using our system, you can rapidly and accurately identify the expression profiles of more than 120 different cytokines and other proteins at very inexpensive cost. Furthermore, the experiment can be performed at a general laboratory setting without any specialized equipment and special training.

RayBio®  Cytokine Antibody Arrays use a proprietary, patent-pending technology for high-throughput analysis of cytokine expression. The RayBio® procedure is simple and straightforward:

Step 1. Incubate the array membrane with your sample.
Step 2. Incubate the cytokine-bound membrane with a cocktail of biotin-labeled antibodies.
Step 3. Incubate the array membrane with HRP-conjugated streptavidin.
Step 4. Detection
