    Abstract:
    An improved silver-ammonia staining method for DNA on polyacrylamide gels is described. In this method, staining of DNA using silver-ammonia complex allows high sensitivity, low cost, low toxicity, and simple protocol without requiring fixation and sensitization steps. The protocol takes less than 40 min to complete, with a detection limit of 1.5 pg of single DNA band on polyacrylamide gels, approximately 30-fold higher than that of original silver-ammonia staining method. Furthermore, this novel technique not only exhibits high sensitivity for large DNA fragment, but also shows a better trend to detect low-base-pair DNA compared with other silver staining methods.
