AAT Bioquest's anti-rabbit secondary antibodies are affinity-purified antibodies with well-characterized specificity for rabbit immunoglobulins and are useful in the detection, sorting or purification of its specified target. To minimize cross-reactivity, our goat anti-rabbit IgG whole antibodies are cross-adsorbed against human IgG and human serum prior to conjugation. This antibody was purified through affinity chromatography and conjugated to Cy3 (ex/em = 555/569 nm).
