Fig. 6 Enhancer Trap Database Fig.6. A page from the Enhancer-Trap Database. The database is compiled on Microsoft Access and contains separate data tables for pattern descriptions, images, line stability, genetic data, mutant phenotypes and screens of the population. Key word searches can be carried out on any field. Lines of interest can then be cross-referenced with a separate image-base containing all available high-resolution images catalogued by line number.
