However, with conventional techniques (e.g. small scale cultivations in shake flasks), it is very tedious to establish optimal conditions for cell growth and protein expression, as the start of protein expression (induction time) and the degree of phosphate limitation have to be determined in numerous concerted, manually conducted experiments.
The cg10062 gene was amplified from genomic DNA of C. glutamicum and fused into the start codon of expression vector pET3b, resulting in the pET cg10062) construct.
Analysis by whole-mount in situ hybridization shows that cHes6-1 is expressed throughout the developing nervous system and that the start of its expression coincides with the onset of neurogenesis at neural plate stages [25] (Fig. 2).
The monoclonal mouse SSEA1 antibody was used to label early germ cells before the start of DDX4/VASA expression (which does not begin until around day 10 postpartum [ 41]).
These results suggest that the morphological transformation of SSCs and the start of the expression of specific markers indicate that SSCs can be reprogramed during long-term culture under specific conditions.
Ra1 expression patterns are correlated with these differences, so that in Miscanthus, which only has long branches with spikelet pairs, there is a delay in the start of ra1 expression.
Hence, a molecular analysis is warranted that elucidates which components of the immune system are upregulated over the time course of an infection, especially during the start of the expression and peak activity at approximately days 3 5 after infection in T. molitor (Haine et al. 2008b).
The predictive potential of this data is predicated on the fact that within 2 to 4 weeks after the start of therapy, gene expression in responsive patients, as measured by DFA, became more like that in healthy controls, while gene expression in nonresponsive patients became less like that in healthy controls.
Consistently, proliferating cells in the proximal germline did not appear before the start of HIM-3 expression.
The presence of a gene in this location is strongly supported by a large number of spliced ESTs containing at least one GT/AG splice site, a Genscan prediction of 2 exons, a CpG island that spans the first exon and the probable transcription start site, and detection of expression in multiple tissues.
