2017-09-01 · The TB1 tube, contains long peptides derived from ESAT-6 and CFP-10 (TB-7.7, present in QFT-GIT, has been removed), and it is designed to induce a specific CD4 T cells response. TB2 contains both the same long peptides of TB1 and newly designed shorter peptides to induce interferon (IFN)-γ production by both CD4 and CD8 T-cells.

It is manufactured by Turkey′s Baykar company primarily for the Turkish Air Force (TAF). The TB1 is accompanied by the TB2, the two blade options in the Truss range, as well as two mallets designs in the shape of the TM1 and TM2 putters. TaylorMade have broken new ground with the launched of the Truss putters with what they describe as a “striking hosel design” – and they will be flat sticks which divide opinion.
