General stain-free western blotting protocol
2 Oct 2026Traditional western blotting can be time-consuming, with data quality often assessed only at the end of the experiment. Bio-Rad’s Stain-Free Western Blotting Workflow enables you to monitor protein separation, verify transfer efficiency and assess data quality throughout the process.
This step-by-step protocol covers both chemiluminescent and multiplex fluorescent western blotting, using ChemiDoc imaging systems and Image Lab software to support accurate total protein normalization and reliable protein analysis.
Download the free protocol to discover how to:
- Reduce western blotting time from 16 to just 5 hours.
- Verify protein separation and transfer efficiency.
- Improve data reliability through total protein normalization.
- Streamline imaging and analysis of chemiluminescent and fluorescent western blots.

Western BlottingWestern blotting equipment is used to transfer and identify specific proteins within a sample, reveal protein modifications, as well as give a semi-quantitative estimation of their concentration. Western blotting equipment includes all apparatus necessary to transfer proteins from gel to membrane and subsequent processing steps. Protein transfer can be performed by electroblotting with wet, semi-dry and dry transfer systems onto nitrocellulose and PVDF membranes. Blocking, washing and labeling of membranes follows, involving buffers, blocking reagents, blotting / incubation trays, labeling reagents, immunoblotting assays, antibodies and conjugates. Automated equipment for these steps is available to accelerate your lab workflow. Finally, detection and imaging of proteins can be conducted using gel documentation and imaging systems.
