The phrase "abundant levels in" is correct and usable in written English.
It can be used when discussing quantities or concentrations of something that are plentiful or excessive within a particular context or subject area.
Example: "The research indicated that there are abundant levels in the soil of essential nutrients necessary for plant growth."
Alternatives: "high concentrations of" or "plentiful amounts of".
While β-glucans and extensins are present in abundant levels in unpollinated pistils, they decrease in abundance and become undetectable in the style as the pollen tubes pass by.
This could be due to bias in the DNA extraction method used, although Bacteroidetes have previously been detected at abundant levels in fecal samples from other individuals using the same extraction methods [8] and amplification protocols [29] in our group.
The surface marker CD271 was present at abundant levels in late OA cartilage.
ACTB mRNA is expressed at moderately abundant levels in most cell types and its protein plays a key role in the cytoskeleton maintenance.
Strikingly, extensins were not detectable in the stigma with the antibodies used, but were present at abundant levels in the intercellular spaces of the style transmitting tissue.
IGLL5 was also detected at abundant levels in the supernatants of the above lysates, suggesting that it is a secreted protein (Additional file 1: Figure S3C-D).
Consequently, the expression of splice type I and II appeared to be tightly regulated in a similar manner, exhibiting an abundant level in the embryo, and decreasing slightly during the pupal stage to the adult level.
Semi-quantitative RT-PCR using specific primers for TNF-α, MIP-2 (CXCL2) and IL-1β showed that LPS treatment caused the amount of TNF-α mRNA to slightly increase compared to the already abundant levels found in untreated cells (figure 2 and 3).
The cell-specific stainings revealed abundant levels of granulocytes in and near the inflamed lesions, whereas they were undetectable in the adjacent normal mucosal tissue in MMP9 −/−:Plg −/− mice.
It is also worth noting that the expression of PNMA5 mRNA per cell varied consecutively from undetectable to abundant levels and not in all-or-none fashion.
A recent human cadaveric study revealed the presence of aggrecanase-generated aggrecan fragments and abundant levels of ADAMTS5 in human IVDs, regardless of the level of disc degeneration, based on magnetic resonance imaging (MRI) grade classification [ 11].
