All index proved that the P5776 cDNA library constructed in this research had high quanlity and could be used for further ESTs sequencing and analyzing. The amplified library of P5776 was screened on white-blue plates, and more than 5,000 white-clones were selected to culture in 96-well plates, then the high quanlity plasmids of white-clones were extracted by traditioal alkaline-lysis method using the Vitagene?96-easy plasmid extract kit. Through PCR primered by T3( the vector has T3 RNA polymerase promoter ), the target fragments of inserts were get. Then the inserts were taged by four different fluorescence-dye, and fractionated by capillary in ABI Prism? sequencer. More than 5,000 5′-ESTs had been sequenced and through rough selecting, 4,747 ESTs were remained for further research. Among the remained ESTs, more than 90% have longer lenth than 500bp, and there are less than 5% unable-read bases in every sequence.
