A magnetic conjugation kit from Innova Biosciences, Cambridge, UK, is the latest addition to the company’s line of particle conjugation technologies. The new kit enables researchers to conjugate antibodies and proteins covalently to 0.5 µm magnetic particles without the need for extensive optimization of the conjugation reaction, thereby saving precious antibody or protein. The kit is suited for use in immunoprecipitation experiments, as covalent attachment provides a more stable alternative to noncovalent antibody attachments using traditional protein A or protein G resin. The specially treated iron oxide magnetic particles offer a balance between high surface area and fast separation. For more information, visit Innova Biosciences.
