摘要: The cDNA sequence coding for human basic fibroblast growth factor (bFGF) has been cloned downstream of a transcription promoter recognized by the bacteriophage T7 RNA polymerase. Initiation translation at fgf gene coupled to upstream fragment phi 10 gene. Expression in this system can lead an accumulation approximately 40 mg/liter/A600 unit bFGF. This material be purified close homogeneity from soluble protein extract on heparin-Sepharose column. bFGF so obtained shown have bioactivity indistinguishable placental mitogenicity, synthesis plasminogen activator, and angiogenesis assays.
