摘要
Objective Molecular cloning and sequencing of the human matured fragment of human nerve growth factor(NGF) gene. Methods Extracting the human genomic DNA from the white blood cells as templates, the gene of NGF was cloned by using PCR and T vector cloning method. Screening the positive clones and identified by the restriction enzymes, and then the cloned amplified fragment was sequenced and analyzed. Results DNA sequence comparison the cloned gene of NGF with the GenBank (V01511) sequence demonstrated that both of sequences were identical, 354bp length. Conclusion Cloning the NGF gene from the human genomic DNA has paved the way for further study on gene therapy of nerve system injury.
