<p>A cDNA library is prepared by extracting the whole of mRNAs from human fetal lung fibroblasts. From this library is cloned a cDNA which codes for TCF-II along its whole length by using a synthetic oligonucleotide probe which codes for an N-terminal amino acid, and the whole base sequence of the cDNA is determined. A large amount of TCF-II is expressed in mammalian cells transformed by a plasmid containing the cDNA and the TCF-II thus derived from the transformed cells is purified. The purified TCF-II is useful as a liver cell growth factor or a tumor cell killing active factor in the medical field or the like.</p> |
