Trypanosoma brucei (T. brucei) subsp. brucei, strain Lister 427 VSG 221 (TetR T7RNAP) was deposited to BEI Resources as a bloodstream form cell line that expresses the T. brucei variant surface glycoprotein (VSG) 221 (also referred to as MITat 1.2), T7 RNA polymerase (T7RNAP) and the tetracycline repressor (TetR) genes. The parental strain of Lister 427 VSG 221 (TetR T7RNAP), strain Lister 427 VSG 221 (BEI Resources NR-42009), is a single-antigen isolate of strain Lister 427. Strain Lister 427 is a virulent lab strain that was isolated in 1960 from a sheep in Uganda and transferred to the Lister Institute in London in 1961.

T. brucei subsp. brucei, strain Lister 427 VSG 221 (TetR T7RNAP) is a transgenic bloodstream form cell line that co-expresses the T7RNAP and TetR genes as well as VSG 221.

Each vial of NR-42011 contains approximately 0.5 mL of culture in 10% glycerol.
