The phrase "a too low concentration" is not correct in standard written English.
The correct form would be "too low a concentration" or "a concentration that is too low."
Example: "The experiment failed because there was too low a concentration of the reactant in the solution."
Alternatives: "an excessively low concentration" or "a concentration that is insufficient."
If the affinity of the antibody from a primary infection is too low (or is present in too low concentration) for a different serotype of Dengue virus, the virion is not neutralized and the secondary infection is enhanced (Guzman and Vazquez 2010; Heinz and Stiasny 2012).
Too low concentration of potassium in the dialysate, diabetes mellitus, advanced age and dialysis performed after the weekend break are important factors that increase the risk of SCD [ 26, 29].
This group included nine spots that contained peptides either at too low concentration or that exhibited adverse fragmentation behaviour resulting in poor spectra that were difficult to interpret, and 38 spots showing no significant homology to any protein in the database or that matched proteins of an unknown function.
Details regarding the three treatment failures are provided in Table 3.> -wrap-foot> days days of treatment; d/at, days after completed therapy; WT, wild-type 23S rRNA gene sequence; NA, not assessed (specimen not available and too low concentration of M. genitalium DNA for 23S rRNA gene sequencing, respectively); PMNL/hpf, polymorphonuclear leucocytes/high power field.
In our studies we have found that EEP had only a modest effect on NF-κB nuclear localization in U87MB cells, which could be a consequence of too low concentrations of NF-κB-inhibiting compounds in the extract we used in our experiments.
In a previous work with spruce [ 22], it was shown possible to consume xylose down to a concentration below 1 g L-1, indicating that the problem is not a too low xylose concentration per se.
If this last reaction step is not fully completed, e.g., due to a too low Cd oleate concentration, a submonolayer (ML) of Pb-atoms should remain on the surface.
The reason might be a too low plasma concentration of applied LPC resulting in complete binding and neutralization by serum proteins and consequently reduced bioavailability of the free unbound form, a prerequisite for their biological effects including IL-8 upregulation [11,30] (Fig. 2B).
Furthermore, the milk samples obviously contained too low concentrations of phthalates and metabolites to permit a more comprehensive and detailed discussion of actual concentrations in this matrix.
