Southwestern and gel renaturation experiments with the use of purified protein fractions revealed that TCF-1 alpha activity is derived from a family of 57- to 53-kD proteins that are abundantly expressed in mature and immature T-cell lines ( Jurkat , CCRF-CEM ) and not in mature B cells ( JY , Namalwa ) or nonlymphoid ( HeLa ) cell lines .
