Figure Legend Snippet: A schematic of the native protein antigen “reverse capture” microarray platform. Well-characterized monoclonal antibodies are printed onto a glass slide. Native protein antigens derived from cell lines or cancer tissues are immobilized onto the array by the printed monoclonal antibodies, with the corresponding antigen captured by a specific monoclonal antibody. Using the immobilized antigens as bait, labeled autoantibodies from a patient and control are then allowed to react with the immobilized antigen. The amount of fluorescent dye-labeled autoantibody between test and control will determine reactivity with the immobilized antigen. We termed this array a “reverse capture” microarray since the standard nomenclature for “capture” refers to the analyte/antigen and not the antibody.
Techniques Used: Microarray, Bioprocessing, Derivative Assay, Labeling, Control
Figure Legend Snippet: Whole proteome lysate fractionation microarray. Tumor or cell lysates are separated into distinct fractions using a 2-D liquid chromatography fractionation strategy where the 1st dimension is separation by isoelectric points and the 2nd dimension is separation by hydrophobicity. Following the 2nd dimension, the fractions are arrayed onto nitrocellulose coated microscope slides. The slides are then incubated with fluorescent dye-labeled serum antibody isolated from cases and controls. The informative spots on the arrays and their corresponding fractions containing the associated antigens are then validated and the protein antigens subsequently identified by mass spectrometry.
Techniques Used: Fractionation, Microarray, Liquid Chromatography, Microscopy, Incubation, Labeling, Isolation, Mass Spectrometry
Figure Legend Snippet: This figure is an image of a whole proteome breast cancer lysate microarray slide scanned for fluorescence after incubating with antibodies isolated from serum from a patient with late stage breast cancer that have underwent autologous tumor vaccination. Post-vaccination antibodies were labeled with Cy3 (green) fluorescent dye, and pre-vaccination antibodies from the same patient were labeled with Cy5 (red) fluorescent dye. Note that there was little reactivity from the pre-vaccination antibodies, but numerous post-vaccination reactive “spots” are seen.
