Figure 3

Gene-expression profiles represented as copies per cell, derived by normalization from the values obtained in the 74 libraries used. (a) Mitochondrial ribosomal protein L20; (b) GW128 protein; (c) RAB5C, member of the Ras family; (d) Poly(A)-binding protein, cytoplasmic 1; (e) glyceraldehyde-3-phosphate dehydrogenase (GAPDH); (f) eukaryotic translation initiation factor 5A. (g) Repartition of GAPDH frequency (in number of tags) as a function of the size of the library from which that frequency was deduced. Three tags are shown that belong to the strictly minimal transcriptome set (d-f) and three tags not belonging to that set (a-c).
