Chromosome-specific cDNAs/STSs. Progress report, September 1, 1991--February 28, 1992
This project has three main goals: (1) to construct high-quality normalized cDNA libraries from human tissues, (2) to develop methods for isolation of chromosome-specific cDNAs, (3) to contribute sequence information to the expanding cDNA/EST database. Our short term goal has been to construct a very high quality cDNA library from a 3 month post-natal total human brain. Several libraries were constructed and carefully characterized by DNA sequencing and restriction analysis while protocols were being streamlined. We have now generated a library which has the following main features: (1) very high complexity (10{sup 7} recombinants), (b) short poly (A) tails; (c) long size inserts (1 kb average); (d) undetectable co-cloning events; (e) background of non-recombinants. The next step will be to generate and test a normalized version of this brain cDNA library. Subsequently, single-stranded versions of the normalized library will be utilized for isolation of chromosome 13-specific cDNAs.
