Innova Biosciences, Cambridge, UK, has launched the AbPure magnetic purification system. The system is based on protein A magnetic beads, which have a high affinity for immunoglobulin (IgG) molecules and allow scientists to purify small quantities of antibody from complex mixtures. While purification technologies based on protein A are well known, they introduce substances that interfere with antibody conjugation reactions, forcing further clean-up steps and losses of valuable material. According to the company, the purification system contains novel buffer compositions that are compatible with every conceivable approach to conjugation. For more information, visit Innova Biosciences.
