Introduction
Recent technological advances by RayBiotech have enabled the largest commercially available glycosylation antibody array to date. With the Human Glycosylation Array 8000, researchers can now efficiently obtain glycosylation profiles in their samples. The glycosylation profiles of 8000 human proteins can be simultaneously detected, including, but not limited to, cytokines, chemokines, adipokines, growth factors, angiogenic factors, proteases, soluble receptors, soluble adhesion molecules in cell culture supernatants, serum, plasma and other samples types.
Capture antibodies are printed onto glass slides and the glycans on these capture antibodies are removed. The glass slide arrays come pre-blocked and are ready to be incubated with samples. After incubation with samples and washing to remove unbound proteins, five unique biotin-labeled lectins are incubated with the array to allow binding to the glycans from captured target proteins. Streptavidin-conjugated fluorescent dye (Cy3 equivalent) is then added to the array. Finally, the glass slide is dried and laser fluorescence scanning is used to visualize the signals. These signals are then compared to the array map to identify glycosylated proteins present in the samples.

Application Data/Notes
Typical Results
The following figure shows the RayBio® Human Glycosylation Antibody Array 507 probed with conditioned media sample. The images were captured using a Axon GenePix laser scanner. The strong signals in row 20 and the upper left and lower right corners of each array are Positive Controls, which can be used to identify the orientation and help normalize the results between arrays.
