印渍术(Blotting)是近十多年来发展的新生物技术之一,它结合了凝胶电泳的高分辨率和酶染色 技术的高灵敏度,结果又能长期保存。目前电印渍装置多为电洗脱式,价格昂贵,需大量试剂和较长的转移时间。我们参考Svoboda等人的设计原理自制一套以碳为阳极,铜皮为阴极的印渍装置,报道如 Blotting is one of the new biotechnologies developed in the past more than a decade. It combines the high resolution of gel electrophoresis and the high sensitivity of enzyme staining technology. The result is long-term storage. At present, electroprinting devices are mostly electroelution type, which is expensive and requires a large amount of reagents and a long transfer time. We refer to the design principles of Svoboda et al. to create a set of printing devices using carbon as the anode and copper as the cathode.
