Polyclonal Antibodies

Polyclonal antibodies recognize multiple epitopes on the same target protein and therefore can offer strong signal-to-noise as the binding at multiple sites allows for many detection molecules to bind.

Antibodies Inc is proud to offer several product lines and flavors of polyclonal antibodies. Rabbit polyclonals are an industry standard for polyclonal antibodies because the medium size of rabbits allows for larger pools of serum. With a focus in both neuroscience and cancer research, our PhosphoSolutions line specializes in phosphospecific rabbit polyclonal antibodies.

Chicken polyclonals have grown in popularity especially when performing multiplex analysis using secondary antibodies. We offer the complete product line from Aves Labs: a pioneer in the use of chickens for the production of polyclonal research antibodies. Evolutionarily removed from mammals, chickens mount a vigorous immune response to mammalian gene products, resulting in high-affinity IgY antibodies. A unique species like chicken is also perfect for multiplexing applications, with low cross-reactivity to other species.

Antibodies Inc offers polyclonal centromere antibodies which are purified IgG derived from human anti-centromere positive serum (CREST patient serum). Useful as diagnostic markers in assays such as IHC and ICC, as well as controls in ANA diagnostics, they help identify autoimmune reactions.
