For reconstitution, we recommend adding 100 µL distilled water to a final antibody concentration of about 1 mg/mL. To use this carrier-free antibody for conjugation experiments, we strongly recommend performing another round of desalting. (Zeba Spin Desalting Columns, 7KMWCO, 0.5 mL, Product # 89882)
JAB-1 is a 38 kDa protein which was originally described as a coactivator for cJUN. It is present in a large protein complex called the "Signalosome", which has been proposed to play a signaling role in mammalian cells. This protein complex appears to be analogous to the COP9 complex in plants, which is important in light-mediated plant development. Although the specific function of JAB-1 in this complex is unclear, it has recently been implicated in targeting proteins for degradation by the proteasome.
