The overall scheme of mutagenesis, plant propagation, and mutant library generation is shown in Fig. 1.
Second, DGS method has several limitations involved in labor, cost, and amount of material: (a) this method needs the generation of two rounds of plasmid libraries and the propagation of plasmid libraries, (b) this method costs higher than microarray platform and DK, (c) a large amount of starting material DNA is required.
E. coli strain ElectroMAX DH10B™ (Invitrogen) was used for routine plasmid propagation, library construction and screening, and recombinant protein production.
Analysis of EST abundance in a contig can provide insights to gene expression levels, although this information must be taken with caution due to cloning and replication bias resulting form library construction and propagation steps.
Escherichia coli strain TG1 (supE thi-1 Δ lac-proAB) Δ lac-proABM) 5 (rK− mK−) [F' traD36 proAB lacIq ZΔ mcrB-hsdSMused as a host for the construction of phage display libraries, as well as for propagation of the wild-type helper phage, VCSM13 (Stratagene, USA).
The ligation mixture was transformed into GC5 competent bacteria for propagation and isolation of the library DNA.
For the construction of entry and destination vectors containing a toxic ccdB gene competent Escherichia coli Library Efficiency DB3.1™cells (Invitrogen), were used for propagation according to the manufacturer's recommendations.
The CADNA library enables one to estimate round-off error propagation using a probabilistic approach.
We use the SumProduct Belief Propagation algorithm, implemented in the Dimple library [ 20] to compute approximated marginals of every hidden variable, given the regulation network, the parameter set, and the expression values.
To maintain high library diversity, the peptide phage library was first propagated in a rich medium to yield the wild-type peptide library followed by second-round propagation in a methionine-deficient Hpg-supplemented medium containing the methionine biosynthesis inhibitors to generate the Hpg-encoded peptide phage library.
