The UK HGMP Resource Centre's collection of human partial cDNA sequenc
es (ESTs) have been examined for suitability for mapping by PCR on a p
anel of somatic cell hybrids. The chromosomal assignments of 92 ESTs w
ere determined with a monochromosomal hybrid panel, and a subset of 45
were linked to genetic markers with a panel of whole-genome radiation
hybrids (WG-RHs). These results demonstrate the potential of WG-RHs t
o construct a transcript map of the human genome.
