PTM Specific
Phospho-Specific
Because they bind to multiple epitopes, polyclonals excel at detecting subtle post-translational modifications (PTMs) with high sensitivity.

Low Background
Affinity Purified
Our top-tier polyclonals are antigen affinity-purified to remove non-specific immunoglobulins, ensuring clean, reproducible backgrounds.
View PurifiedThe Biorbyt Difference: Antigen Affinity Purification
We solve the historical challenge of polyclonal background noise through strict Antigen Affinity Purification processes.
By passing raw serum over a column coupled with the specific immunizing peptide, we isolate only the target-specific antibodies. This eliminates cross-reactive host immunoglobulins, giving you monoclonal-like specificity with polyclonal sensitivity.
Unrivaled Signal Amplification in Difficult Assays
Because a polyclonal antiserum contains multiple antibody clones that recognize different parts of the same protein, they are uniquely powerful in assays where target epitopes might be denatured, cross-linked, or masked.

Strong Capture
Choose polyclonals when your research demands:
- High Sensitivity: Multiple antibodies binding to a single target massively boosts secondary detection signals.
- Variant Detection: Easily identify protein isoforms, splice variants, or closely related homologs across species.
- Harsh Conditions: Reliable binding even when standard fixation or heat-denaturing destroys a single specific epitope.
