  11. The full coding regions of bdnf genes were amplified from the genome of tylototriton taliangensis, phrynocephalus hongyuanensis, japalura splendida and cyclophiops major, respectively by pcr with the primers designed on the sequence of human bdnf gene. the pcr products were cloned into the vector pucis of esherichia coli. sequence analysis showed that the coding regions of three reptiles are the same ( 741 bp ) in length and these bdnf genes encode a peptide of 246 amino acid residues while that of tylototriton taliangensis is 744 bp in length and encodes a peptide of 247 amino acid residues

    根據已有的人bdnf結構基因的全長序列設計了一對引物，利用pcr技術分別從大涼疣螈（ tylototritontaliangensis ） 、紅原沙蜥（ phrynocephalushongyuanensis ） 、麗紋龍蜥（ japalurasplendida ）和翠青蛇（ cyclophiopsmajor ）的基因組dna中擴增到目的dna片段，並將其分別克隆到大腸桿菌載體中，然後對所獲得的陽性克隆進行測序。
