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.

The subgroups below are organised by format, conjugation, validation method and target family, to guide navigation to the right collection.

Hantavirus

Primary antibodies and reagents against hantavirus targets, curated to support infection and immune-response research.

Browse Hantavirus →

ImmunoSwitch

Unmatched primary-secondary antibodies can now be bridged together with ImmunoSwitch antibodies.

Browse ImmunoSwitch →

Chimeric Antibodies

Primary antibodies combining the variable domain of one species with the constant region of another, engineered for isotype switching and cross-species panel design.

Browse Chimeric Antibodies →

IHC Guaranteed Antibodies

The primary antibodies are validated on formalin-fixed, paraffin-embedded tissue, with confirmed epitope survival and documented antigen retrieval for reliable tissue staining.

Browse IHC Guaranteed Antibodies →

Isotype Controls

Class-matched control immunoglobulins that establish non-specific background for flow cytometry and immunostaining. Grouped by host species and immunoglobulin class.

Browse Isotype Controls →

Knockout-Validated Antibodies

Confirmed against gene-knockout material, knockout antibodies are met with the most stringent specificity standard, curated for experiments where cross-reactivity cannot be tolerated.

Browse Knockout-Validated Antibodies →

Loading Control Antibodies

Housekeeping-protein antibodies used to normalise sample loading in macromolecular analysis. Constitutively expressed targets across multiple host species and formats.

Browse Loading Control Antibodies →

Lyophilized antibodies

Freeze-dried antibody formats for ambient-temperature storage and transport without a cold chain, reconstituted to the required concentration at point of use.

Browse Lyophilized antibodies →

CD Markers

A panel of anti-CD markers for resolving immune and stem cell populations by surface phenotype, curated to support immunophenotyping across flow cytometry and IHC.

Browse CD Markers →

Tag Antibodies

Antibodies against constant epitope tags for detecting, immunoprecipitating and purifying recombinant constructs independently of the fused target.

Browse Tag Antibodies →

Trial Size Antibodies

Reduced-quantity formats for validating antibody performance in a given application before committing to a standard vial, with the identical lot available at full size.

Browse Trial Size Antibodies →

Conjugated Primary Antibodies

Primary antibodies supplied with the detection label already attached, removing the secondary step for multiplex flow cytometry and multicolour imaging. Organised by conjugate.

Browse Conjugated Primary Antibodies →

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.
