Combining direct antigen-labeling technology with our vast library of array-validated antibodies, RayBiotech has created our largest antibody array to date: the Human L8000 Array. With the L-Series high density array platform, researchers can now detect up to 8000 proteins simultaneously, obtaining a broad, panoramic view of protein expression. Our newly expanded panel includes a wide variety of metabolic enzymes, structural proteins, epigenetic markers, neuroregulatory factors, in addition to our popular list of cytokines, growth factors, receptors, adipokines, proteases, and signaling proteins. Available on both glass slide and membrane formats, this array is ideally suited for biomarker discovery studies and exploratory screens.
Ship us your samples (4 sample minimum) and our experienced service department will perform a high-density array of your choice. We can analyze up to 8000 human, 1308 mouse, or 1500 rat proteins and return to you a full data report. Click the button below to learn more.

How It Works
Through a simple labeling process, the sample proteins are directly conjugated to biotin, eliminating the need for a second antibody to develop the array signals. In this format, unintended antibody interactions are impossible, thus eliminating limitations on the size of the array panel.
Our RayBio® Label-Based Arrays differ from our sandwich ELISA-based arrays primarily in the means of detection. Instead of using a second biotinylated antigen-specific antibody, sample proteins themselves are labeled with biotin prior to incubation with the capture antibodies. Proteins binding to the array can be detected using streptavidin-HRP for chemiluminescence detection or streptavidin-conjugated fluor for fluorescence detection.

The cell culture supernates or serum is dialyzed before biotin-labeling step. Through a simple process, the primary amine of the proteins in the sample is biotinylated, followed by dialysis to remove free biotin. From here, the newly biotinylated sample is added onto the array membrane or glass slide and incubated at room temperature. After incubation with HRP-streptavidin or Fluorescent Dye-Strepavidin, the signals can be visualized either by chemiluminescence or fluorescence. The experimental procedure is simple and can be performed in any laboratory.
