An approach for quick and efficient production of polyclonal antibodies to the target antigen, alpha-synuclein, has been proposed. Two methods have been employed to purify specific rabbit polyclonal antibodies against recombinant human alpha-synuclein, produced by subcutaneous immunization with complete Freund’s adjuvant. It was shown that purification on CNBr-activated Sepharose with immobilized alpha-synuclein resulted in antibody preparation with rabbit serum histidine-rich glycoprotein as a contaminant. Two-stage antibody purification procedure first on Sepharose with immobilized protein G, and then on alpha-synuclein immobilized column helps to avoid contamination and to obtain homogenous antibody preparation. Antibodies recognize different conformations of alpha-synuclein and can be used in a variety of immunochemical approaches, including immunocytochemistry.
