Anti-GGA3 Antibody - Western Blot. Western blot of Affinity Purified anti-GGA3 antibody shows detection of a band at ~110 kD corresponding to GFP-GGA3 fusion protein present in a lysate of HEK293 cells over- expressing the recombinant protein (lane 2, arrowhead). Pre-incubation of antibody with immunizing peptide blocks specific staining (lane 3). MW markers are shown in lane 1 (700 nm channel - red). Approximately 35 ug of lysate was separated on a 16% Tricine gel by SDS-PAGE and transferred onto nitrocellulose. After blocking the membrane was probed with the primary antibody diluted to 1:600. Reaction occurred overnight at 4C followed by washes and reaction with a 1:10000 dilution of IRDye800 conjugated Gt-a-Rabbit IgG [H&L] ( for 45 min at room temperature (800 nm channel - green). IRDye800 fluorescence image was captured using the Odyssey Infrared Imaging System developed by LI-COR. IRDye is a trademark of LI-COR, Inc. Other detection systems will yield similar results.
