[Construction and identification of a full-length cDNA library from Spirometra erinaceieuropaei]

The full-length pBluescript II SK cDNA library of adult Spirometra erinaceieuropaei was constructed by using the SMART method. Data showed that 95.5% of the library was recombinant and the titer of the library was 1.06 x 10(6). The average insert size of the library was about 1.4 kb. Forty-eight randomly selected clones were sequenced. A set of 36 effective expressed sequence tags (ESTs) with the average size of 674 bp was obtained after excluding clones shorter than 450 bp. The unigenes occupied 58.3% of the 36 ESTs. The rate of full-length cDNAs were 57.7% (15/26). The high-quality of full-length cDNA library could be used for large scale EST sequencing.
