This can be a problem, especially in the case of cell-surface receptors, because Abs generated and selected against recombinant proteins may not bind the same protein expressed on a cell surface in its native form and because the expression of some receptors as recombinant proteins is problematic.
Because the expression of cytoskeletal and metabolic genes changes during neuronal development, the typical, constitutively expressed mRNAs ("housekeeping genes") were inappropriate for use as internal standards.
The efficiency of conversion was in general much lower than that observed in early stage IMR90 cells, likely because the expression of p16, p19 and p53 is progressively upregulated in late passage cells (Fig. 5a).
The discussion will be limited herein to ERRα and ERRγ because the expression of ERRβ is higher in embryonic tissues; therefore, less is known regarding its role in adult physiology.
That could make for much more rewarding socializing, work, or play in virtual worlds, because the expression of a virtual body double or otherworldly avatar could perfectly mimic that of a person's real face.
ATF4 is thought to play a dominant role in inducing CHOP expression in response to ERS because the expression of ATF4 is upregulated when eIF2α is phosphorylated by PERK41.
Because the expression of the cell adhesion molecules is associated with endothelial cell activation, we isolated endothelial cells from the microvessels of the umbilical placenta and examined them for evidence of gene expression of cell adhesion molecules.
We considered Assumption 2 because the expression of C0 is not intuitive.
The incorporation of DHBA may have been restricted because the expression of phaAB1 competes for acetyl-CoA.
This is because the expression of the meniscus height h∝ Rln(δ/a) has been replaced by [20].
It is hard to compare the two strategies with and without the PA feedback directly from Equations 23 and 36 because the expression of η is complicated.
