[i] This table represents information calculated from the sum of both SAGE libraries (136,856 total tags representing 36,300 unique transcripts.)
[ii] Unless otherwise noted, ranges are given as > the first value and ≤ the second value.
[iii] Copies per cell was calculated assuming, or average, 500,000 transcripts in a cell (Hastie and Bishop 1976).
[iv] If a tag matches a gene and an EST, it was counted only as a gene. See Methods for tag-to-UniGene cluster matching algorithm.
