Abstract
Molecular biotechnology is a broad research and development principle encompassing basic research as well as applied industrial developments. Biotechnology is expected to become one of the most important research and development sectors in the next century, but the domestic support industry for the field is severely underdeveloped and at best in its infancy. DNA size marker is frequently employed during research in a purpose of extrapolating the relative size of a DNA fragment or measuring the amount of DNA loaded a sample. However, DNA size marker is not developed for commercialization domestically. Further, liquid suspension containing DNA size marker needs to be kept at a low temperature during storage and shipping. In an attempt to maintain the DNA samples at room temperature for extended period of time, lyophilization of DNA with addition of a nuclease inhibitor was studied. Hae Ⅲ digest of ΦX174 phage DNA has been a useful size marker for low molecualr weight DNA molecules, but the double strand RF form of the phage DNA requires laborious procedures for cell culture and purification. A new plasmid was constructed to generate band patterns which can substitute the Hae Ⅲ digest of ΦX174 phage DNA for a comparable purpose. Gel staining dye was also added to the lyophilized DNA to provide additional convenience such that DNA size marker was ready for use by simple reconstitution of distilled water. DNA size marker appears to be advantageous for development as one can judge the quality of the product by direct observation.
