Primary antibodies are versatile biological reagents used to detect a wide range of antigenic targets. Antibodies against a target of interest are raised in host species such as mouse, sheep, rabbit, rat or goat. The target is often a protein, and is usually from a species different to that of the host. Common target species are human, mouse, rat and veterinary species but can also be viral, bacterial or chemical depending on the area of research.

Our catalogue of high quality monoclonal and polyclonal primary antibodies are suitable for use in numerous applications, including flow cytometry, ELISA, immunohistochemistry, immunofluorescence and western blot. They are available labelled with a variety of fluorescent dyes or proteins including FITC, PE, PerCP and APC, enzymes such as horseradish peroxidase, or biotin for further amplification via labelled streptavidin. Also available without a label, our unconjugated antibodies require a species-specific secondary antibody to enable detection. Please see our Secondary antibodies page for our extensive range.
