Sentence examples for by a poor expression from inspiring English sources

Importantly, the observed lack of 1-indanone conversion is not caused by a poor expression because all PAMO variants were equally well expressed under these experimental conditions (data not shown), thereby pointing towards a low reactivity of PAMO P440L and P440G with 1-indanone like the wild-type enzyme and possibly a lowered uptake of the substrate under non-optimized conditions.

When cells have not yet established well-defined adherens junctions, as shown by the poor expression of E-cadherin at cell cell contacts (left panel), PrPc was mainly detected intracellularly.

The large-scale production of recombinant pharmaceutical proteins is often hampered by the poor expression of their mature, active forms in prokaryotic hosts such as E. coli and by the high costs and the limited scalability of traditional fermenter-based platforms using mammalian cells.
