Anti-Ajuba Antibody - Western Blot. Western blot of Affinity Purified anti-Ajuba antibody shows detection of a 57-kD band consistent with the expected MW for Ajuba (arrowhead). Lanes correspond to 1) HeLa nuclear extract, and 2) HeLa, 3) A431, 4) Jurkat and 5) 293 whole cell lysates. Immunoprecipitation of Ajuba followed by western blotting may result in cleaner background staining. Approximately 5 ug of each preparation was run on a SDS-PAGE and transferred onto nitrocellulose followed by reaction with a 1:500 dilution of anti-Ajuba antibody. Detection occurred using a 1:5000 dilution of HRP-labeled Donkey anti-Rabbit IgG for 1 hour at room temperature. A chemiluminescence system was used for signal detection (Roche) using a 60-sec exposure time. Personal Communication. E. Pugacheva, Fox Chase Cancer Center, Philadelphia, PA.
Anti-Ajuba Antibody - Western Blot. Western blot of Affinity Purified anti-Ajuba antibody shows detection of Ajuba-RFP fusion protein in cell lysates (arrow-head). Lanes correspond to 1) vector only transfection, 2) human Ajuba-RFP, 3) mouse Ajuba-RFP, and 4) mock transfection. Approximately 50 ug of each lysate was loaded per lane for SDS-PAGE followed by transfer onto nitrocellulose and reaction with a 1:1700 dilution of anti-Ajuba antibody. Detection occurred using a 1:10000 dilution of IRDye800 conjugated Gt-a-Rabbit IgG [H&L] ( for 45 min at room temperature (800 nm channel, green). Molecular weight estimation was made by comparison to prestained MW markers (indicated at left, 700 nm channel, red). 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.
