B. Stone et W. Wharton, TARGETED RNA FINGERPRINTING - THE CLONING OF DIFFERENTIALLY-EXPRESSEDCDNA FRAGMENTS ENRICHED FOR MEMBERS OF THE ZINC-FINGER GENE FAMILY, Nucleic acids research, 22(13), 1994, pp. 2612-2618
We have developed and applied a modification of an 'RNA Fingerprinting
' protocol previously published by Welsh and McClelland (Nucleic Acids
Research 19: 5275-5279 1991) such that cDNA fragments which are both
differentially-expressed and enriched for members of a specific gene f
amily can readily be identified. cDNA fragments were amplified with an
arbitrary primer initially used in the reverse transcription reaction
in combination with a member of a primer set which corresponded to a
conserved region within a specific gene family. This technique was use
d to isolate cDNAs encoding a recently described protein kinase as wel
l as an unknown gene that contained a zinc finger. Several other known
genes that contained a zinc finger domain and that were differentiall
y-expressed were also isolated.
