(TF) 1. a dialyzable extract obtained from lysates of peripheral blood lymphocytes that is capable of transferring antigen-specific cell-mediated immunity (delayed-type hypersensitivity) from donor to recipient and also has nonspecific immunostimulatory activity; it appears to contain both protein and RNA but not DNA and to consist of small molecules (mol. wt. less than 10,000). TF is nonantigenic and does not transfer humoral immunity. It has been used in the treatment of a variety of immunodeficiency diseases. 2. elongation f.
