For dry transfer, 2. 2 ®iBlot2 Dry Blotting System User Guide Information in this document is subject to change without notice. 2. The immunoassay uses a membrane made of nitrocellulose or PVDF (polyvinylidene fluoride). 2. WB7103, WB7105, WB 7107 Version F June 4, 2003 IM-1004. 1 Department of Physiology and Biophysics, University of California, Irvine (UCI) DOI. After western blot transfer, the membrane is ready to be probed for your protein, or proteins, of interest. i Table of Contents Table of Contents.....i Important Information.....1 General Guidelines.....3 Preparing Solutions.....5 WesternBreezefi Chromogenic Immunodetection Protocol...7 Troubleshooting.....8 Technical Service.....13. ii. In general, a non-denaturing condition simply means leaving SDS out of the sample and migration buffers and not heating the samples. • Primary antibodies (e.g., Invitrogen™ western blot – validated* primary antibodies) • ™Secondary antibodies (e.g., Invitrogen fluorescently labeled highly cross-adsorbed secondary antibodies) Protocol 1. • ™For wet transfer: Invitrogen Mini Blot Module • ™For semi-dry transfer: Invitrogen Power Blotter System • ™For dry transfer: Invitrogen iBlot™ 2 Gel Transfer Device Protocol 1. Load equal amounts of protein (20 μg) into the wells of a mini (8.6 x 6.7 cm) or midi (13.3 x 8.7 cm) format SDS-PAGE gel, along with molecular weight markers. iBlot™ 2 Dry Blotting System USER GUIDE For dry, electroblotting of proteins from mini-, midi-, and E PAGE ™ gels Catalog Number IB21001 Publication Number MAN0009112 Revision D.0.

DISCLAIMER: TO THE EXTENT ALLOWED BY LAW, LIFE TECHNOLOGIES AND/OR ITS AFFILIATE(S) … General Protocol for Western Blotting Protein separation by gel electrophoresis 1. In these circumstances, it is important to run a western blot in non-denaturing conditions, and this will be noted on the datasheet in the applications section. Summary. The gel is placed next to the membrane and … Click the steps of the Western Blotting protocol below to view the relevant details of each step: Western Blotting refers to the electrophoretic transfer of proteins from sodium dodecyl sulfate polyacrylamide gels to sheets of PVDF or nitrocellullose membrane, followed by immunodetection of proteins using antibodies with fluorescent or chemiluminescent detection. Prepare transfer buffer for wet or semi-dry transfer based on gel chemistry. Prepare transfer buffer for wet or semi-dry transfer based on gel chemistry. August 22nd, 2007 • Aubin Penna 1, Michael Cahalan 1. Run the gel for 5 min at 50 V. 3. Prepare transfer membrane. Western blotting uses specific antibodies to identify proteins that have been separated based on size by gel electrophoresis. Prepare transfer membrane. Traditionally, this has been a manual process that involves incubating the blot in a series of antibody and wash solutions in a tray over several hours. Increase the voltage to 100–150 V to finish the run in about 1 hr. Our western blot protocol includes solutions and reagents, procedure, and useful links to guide you through your experiment.
