When stored for an appreciable length of time radioiodinated antibodies undergo radiolysis leading to a loss in purity and immunoreactivity. The rate of radiolysis can be reduced by the addition of carrier proteins or antioxidants such as ascorbic add which scavenge the free radicals responsible (9). A concentration of 0.1-1% albumin or 0.5% ascorbic acid is commonly used and...
