Figure 1From: An EST resource for tilapia based on 17 normalized libraries and assembly of 116,899 sequence tagsA single high density filter of retinal cDNA libraries hybridized with a rhodopsin probe. The left side of the filter contains ~9,000 clones from an un-normalized library. The right half of the filter contains ~9,000 clones from the normalized library. Normalization has greatly reduced the redundancy of the library.Back to article page
