    Snippet: We utilised the human tRNA Ser anticodon that had been previously modified to produce variants that would recognise UAA, UAG and UGA [41] . To first test their specificity in the cultured cells, readthrough of the efficient termination signals UAAAAG, UAGAAG and UGAAAG were measured in HEK293T cells with the cognate suppressor, the non-cognate suppressors and parent tRNA Ser as the negative control. All test stop signals allowed only < 0.1% readt.....

To first test their specificity in the cultured cells, readthrough of the efficient termination signals UAAAAG, UAGAAG and UGAAAG were measured in HEK293T cells with the cognate suppressor, the non-cognate suppressors and parent tRNA Ser as the negative control. All test stop signals allowed only < 0.1% readthrough with co-expression of either the negative control tRNA Ser or the The Codon following the Slippery Sequence Supports HIV Frameshifting non-cognate suppressors. Cognate suppressors increased readthrough to 9-16% at their respective termination signals 48 h after transfection (Fig. 6A) .
