Primary Antibodies

Essential Detection Reagents

Primary Antibodies

Explore a comprehensive portfolio of primary antibodies for direct antigen detection across the full range of immunoassay platforms. The collection spans polyclonal, monoclonal and recombinant formats validated for western blot, immunohistochemistry, immunofluorescence, flow cytometry and ELISA, with reactivity across human, mouse, rat and further species. Each format is curated to suit a distinct experimental need: multi-epitope polyclonals for signal amplification, single-clone monoclonals for specificity, and sequence-defined recombinants for reproducibility.

Monoclonal Antibodies

Single-clone antibodies delivering high specificity, low background and lot-to-lot consistency, grouped by host across mouse and rabbit.

Browse Monoclonal Antibodies →

Polyclonal Antibodies

Multi-epitope antibody populations that amplify signal from low-abundance targets and tolerate antigen variation, suited to immunoprecipitation and denatured-protein detection.

Browse Polyclonal Antibodies →

Post Translational Modifications

Modification-specific antibodies that resolve the regulatory state of a target, spanning phosphorylation, methylation and acetylation marks at defined residues.

Browse Post Translational Modifications →

Recombinant Antibodies

Sequence-defined antibodies offering the highest batch-to-batch reproducibility, produced animal-free and engineerable into alternative formats.
