The coding sequence of DsRed.T3 was amplified from pQE31‑DsRed.T326 using the primer pair DsRedTUp2 (5'TAGGATCCCCACTAGTCGCCACCATGGCC TCCTC) and DsRedTDo (5'ATAGTTTAGCGGCCGCTCAGT GATCAGACAGGAACAGGTGGTGG) designed to incorporate 5' BamHI and nested 3' BclI and NotI sites. Following digestion with BamHI and NotI, the amplified gene cassette was subcloned into the multi‑copy yeast expression vector pAS1NB under control of the PGK1 promoter and the resultant vector named pAS1NB‑DsRed.T3. The super ecliptic pHluorin (SEP) gene was amplified from the template pGEX‑2T‑SEP27 using the primer pair PHUp1 (5'GGGATCCTGGTCTTCGGGTGGAAGTAAAGGAG) and PHDo1 (5'‑ATAGTTTAGCGGCCGCTCAGTGATCAGATT TGTATAGTTCATCC) designed to incorporate flanking 5' BamHI and 3' NotI sites. The SEP gene cassette recovered by PCR was digested with BamHI and NotI, and cloned into pAS1NB‑DsRed.T3 digested with BclI and NotI to produce this vector. The expression product from this vector, named the Rosella biosensor, comprises DsRed.T3 fused to SEP with an intervening linker of 9 amino acids (DPWSSSGDL).
