  • (18) A Tn5tac1 insertion just inside the 3' end of cysQ, with its isopropyl-beta-D-thiogalactopyranoside-inducible tac promoter pointed toward the cysQ promoter, resulted in auxotrophy only when isopropyl-beta-D-thiogalactopyranoside was present; this conditional phenotype was ascribed to collision between converging RNA polymerases or interaction between complementary antisense and cysQ mRNAs.
  • (19) In addition, a monoclonal antibody (moAb) against the IL2 receptor (IL2-R; anti-Tac) inhibited the spontaneous colony formation from T-CFC of both groups of patients.
  • (20) The artificial secretory molecule of the IL-2 receptor named "bottom-less" receptor was able to react with anti-Tac antibody and to bind IL-2.

Tan


Definition:
