Two studies were done in which SAGE data were collected. One study was directed at the definition of photoreceptor-enriched or specific genes (Blackshaw et al. Cell, 2001) and the other used SAGE to find genes that are temporally regulated in development (Blackshaw et al. PloS-Biology, 2004). Both studies include a large number of in situ hybridization images. The data are organized in two places on this web site.
