| Abstract: | According to the sequence of PCI246,two primers were designed.The 5'end and 3' end of 70 ku heat shock protein cognate cDNA in crayfish(Procambarus clarkii) were amplified respectively.A 1 184 bp fragment was obtained with the completed sequence of 3'end of the gene.The GenBank accession number is AY357302.The nucleotide identity between this protein and heat shock protein cognate of Bombyx mori was 83%.And the amino acid identity between this protein and heat shock protein cognate 3 of Drosophila melanogaster was 85%. |

| Keywords: | complete sequence of cDNA rapid amplification of cDNA ends homology 70 ku heat shock protein cognate |
