Abstract

New forms of CSF-1 are provided which relate to N-terminal truncations. Specifically, N-.gradient.3 terminal truncations of the short form of CSF-1 have been found to be particularly advantageous. These forms may have a C-terminal truncation at a variety of different amino acids beyond position 150.
