title: Bacillus subtilis contains multiple forms of somatostatin-like material.
abstract: Extracts of B. subtilis contain somatostatin-like immunoactivity (1-20 pg per g wet weight cells). Two major forms were detected, one with reactivity in both N- and C-terminal immunoassays similar to somatostatin-28 and a second form reactive only in the C-terminal specific immunoassay similar to somatostatin-14. Both forms were active in a bioassay and the bioactivity was neutralized in the presence of antibody to the central, biologically active part of somatostatin-14. Preconditioned medium contained no detectable somatostatin whereas conditioned medium had 80-380 pg per liter.
