Secondary Antibodies for Western Blotting
Achieve clear western blot data with minimal optimization using secondary antibodies that provide strong signal amplification and low background, even in multiplex workflows.
Explore products designed to support reliable western blot performance:
- Cross-Adsorbed Secondary AntibodiesMany of Bio-Rad’s polyclonal secondary antibodies are cross-adsorbed against other species to remove non-target Ig binding.
- Isotype-Specific Monoclonal Secondary AntibodiesRecombinant monoclonal antibodies, to mouse IgGs with multiple formats, only detect a single isotype, eliminating any cross-reactivity.
- StarBright Blue Secondary AntibodiesAntibodiesAnti-rabbit and anti-mouse secondary antibodies conjugated to Bio-Rad’s unique bright and stable StarBright Blue SBB520 and SBB700 Dyes for higher sensitivity detection, only needing short exposure times.
- TidyBlot ReagentTidyBlot eliminates obstruction by denatured IgG heavy and light chains in western blots by only binding native nondenatured antibodies, producing publication-quality data.
