The phrase "ascertain the expression of" is correct and usable in written English.
It can be used when you want to determine or find out the specific way something is expressed or articulated.
Example: "In order to improve our communication strategy, we need to ascertain the expression of our target audience's needs and preferences."
Alternatives: "determine the articulation of" or "identify the phrasing of".
Methods: RT-PCR was used to ascertain the expression of RNF138 mRNA in the glioma cell lines U251, SHG44, U87, A172, and U373.
Using high-quality matches (>85% identity, >100 bp overlap, E-value < 1.0e-15) wereere able to ascertain the expression of 316 orthologous genes (see Additional file 1). Figure 4 shows the quality of the matches.
To ascertain the expression of activated Notch1 in gastric tumour tissue, we examined the expression of ICN1 in the training and validation sets of specimens and matched the non-tumour specimens by IHC staining.
To determine the option values on the loan portfolio, the output of our conceptual framework, we must ascertain the expressions for the put and call options.
Because many of our ongoing gene engineering experiments rely on the vasa promoter (Papathanos et al. 2009) for expression of enzymes in the germ cells, we wanted to ascertain the expression pattern of this promoter when inserted at the X1 docking site.
We next sought to ascertain the expression pattern of EMT drivers along the EMT Spectrum.
In order to ascertain the expression pattern of the three identified cell-death-related genes in response to Foc inoculation in banana, suspension culture cells of banana (cv.
Because the incorporation of halogenated nucleotides into DNA could affect gene expression, the fusion experiment involving labeling with halogenated nucleotides is done separately from the fusion experiment for ascertaining the expression status of genes.
As the regulation of SIRT1 has not been investigated in cancer cells lacking ER, in the present study we ascertained the expression and function of SIRT1 by estrogens in ER-negative breast cancer cells and cancer-associated fibroblasts obtained from breast cancer patients.
In order to ascertain whether the expression of VEGF isoforms could be accompanied by inflammatory or anti-inflammatory mechanisms, we analyzed COX-2 and HO-1 levels in whole AT. Figure 3A shows that TAT significantly expressed high levels of COX-2 compared to SAT (p<0.05), while similar levels of HO-1 mRNA were detected in both AT's (Fig. 3B).
To ascertain whether the expression of other COPTs was also response to pathogen infection, rice plants were inoculated with different Xoo strains.
