Normal rabbit serum is collected from New Zealand White animals, a species consistently used in immunological research for its well-characterized antibody response and predictable protein profile. It is centrifuged to remove cellular components and processed to deliver a clean, species-matched matrix for blocking, calibration, and cell culture supplement applications.
As a blocking agent and antibody diluent, normal rabbit serum saturates non-specific binding sites before antibody-based detection systems are applied. In blocking buffer preparation, it provides the protein background your secondary detection step needs to read signal rather than noise. IgG rabbit reference standards can be paired directly with rabbit serum in quantification workflows.
Clotting factors are absent in serum, making it the appropriate fraction for applications where fibrinogen interference would compromise downstream results. For immunohistochemistry and ELISA workflows running rabbit-derived primaries, species-matched blocking with normal rabbit serum is the cleaner technical decision.
Equitech-Bio supplies rabbit serum in documented lots for consistent performance across experimental runs. It works alongside goat anti-rabbit antibody detection systems and normal rabbit serum blocking applications. Research use only.
