The reader must turn to the literature to amplify upon any of these topics. Here we return to the two-colour generatorAVMEL scheme to see how it easily can be adapted to the RRS problem. 

Figure 5.3. Systematic mating ofyeast two-hybrid bait and prey pools. Each yeast ORF was cloned individually into both as a DNA binding domain fusion (bait) and activation domain fusion (prey). The bait fusions were introduced into a MATa strain and the prey fusions were introduced into a MATa strain. The bait and prey fusions were pooled in sets of 96 clones to generate a total of 62 pools of each. The pools were systematically mated (62 x 62) in a total of 3844 crosses. Interacting clones were selected and the bait and prey inserts were PCR amplified and sequenced to determine their identify. Figure adapted from Ito et al. (2001).

Figure 1 Schematic diagrams illustrating the patch-clamp technique. (A) Overall setup for isolating single ionic channels in an intact patch of cell membrane. P = patch pipet R = reference microelectrode I = intracellular microelectrode Vp = applied patch potential Em = membrane potential Vm = Em — Vp = potential across the patch A = patch-clamp amplifier. (From Ref. 90.) (B) Five different recording configurations, and procedures used to establish them, (i) Cell attached or intact patch (ii) open cell attached patch (iii) whole cell recording (iv) excised outside-out patch (v) excised inside-out patch. Key i = inside of the cell o = outside of the cell. (Adapted from Ref. 283.)...

Plants produce an amazing diversity of secondary metabolites that not only play important biological roles in their adaptation to environments but also provide humans with dyes, flavors, drugs, fragrance, and other useful chemicals. However, many of the secondary metabolic pathways are found or are amplified only in limited taxonomic groups. In addition, the compounds are often restricted to a particular... 

Figure 14.8. Enzymatically-amplified TR-FIA ofa-fetoprotein (AFP), using streptavidin-alkaline phosphatase conjugate (SA-ALP) and 5-lluorosalicyl phosphate (FSAP) to generate 5 fluorosalicylic acid (FSA). The FSA comhines with terbium-EDTA to form a bright, fluorescent complex. (Adapted from Ref. 83 with permission.) (01992, American Chemical Society).

Given the absence of well-characterized blank DCLs, it was not possible to say with certainty that the amplified compounds were the result of genuine adaptive behaviour of the DCL at thermodynamic equilibrium. 

Figure 7.7. Schematic representation of gene selection by compartmentalization. Step 1 An in vitro transcription/translation reaction mixture containing a library of genes linked to a substrate for the reaction being selected is dispersed to form a water-in-oil emulsion with typically one gene per aqueous compartment. Step 2 The genes are transcripted and translated within their compartments. Step 3 Proteins (or RNAs) with enzymatic activities convert the substrate into a product that remains linked to the gene. Compartmentalization prevents the modification of genes in other compartments. Step 4 The emulsion is broken all reactions are stopped and the aqueous compartments are combined. Genes linked to the product are selectively enriched, then amplified, and either characterized (step 5) or linked to the substrate and compartmentalized for further rounds of selection (step 6).
