(12) The complete transcriptional unit, incorporating the tac promoter and rrnB transcription terminators flanking the Pf1 coat protein gene, was excised from the expression plasmid and cloned into the intergenic space of bacteriophage R252, an fd bacteriophage that carries an amber mutation in its own major coat protein gene.

(16) Unlike other reported cases of Thp-CLL, fresh leukemic cells from this patient were positive with the anti-Tac monoclonal antibody, which recognizes the receptor for interleukin-2 (IL-2).
(17) SF CD4+ cells from RA and non-RA arthritides expressed the Tac antigen much more frequently than corresponding CD8+ cells (54 and 58% versus 16 and 17%).
(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.
