... ‘[ 15 N]-unlabelling’, where the protein was produced on a medium containing inexpensive 15 NH 4 Cl and the [ 15 N]-labelling of selected residues was suppressed by the addition of amino acids at nat- ural ... abundance [17]. In the case of cell-free protein synthesis, however, the costs of the [ 15 N]- labelled amino acids are hardly limiting, considering that adequat...

... 10] could be the reason of the location-related scion re- sponse. It was described that the auxin synthesised in the apical bud inhibits the growth of the axillary buds [2], and so the location of the ... 0.05). In Pinus radiata high concentrations of auxins and cytokinins were required for early development of the micrograft in vitro. This differed...
