Codante DNA fragment factor inhibiting the proliferation of tumor cells.

摘要

It PRESENTS A DNA fragment has the base sequence represented by formula (I) and encoding a FACTOR INHIBITING PROLIFERATION OF CELLS TUMOR THAT MAY BE OBTAINED preparing a cDNA library from the mRNA OF A CELL LINE SET FORTH DERIVED FROM THE 3T3, amplifying different fragments of DNA putatively encode FACTOR INHIBITING pROLIFERATION OF CELLS TUMOR BY PCR technique, and analyzing the base sequences of the fragments amplified DNA to determine the sequence of DNA base encoding inhibiting factor. In said formula (I) X represents TTC TTT CTA or TTC.
