The phrase "absolute quantitation of the" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in fields like chemistry, biology, or pharmacology, where precise measurement is important.
Example: "The study focused on the absolute quantitation of the protein levels in various samples to ensure accuracy in the results."
Alternatives: "precise measurement of the" or "exact quantification of the".
Absolute quantitation of the metabolites in the biological sample was achieved by reference to appropriate internal standards which are structurally identical but labeled with stable isotopes such as deuterium, 13C, or 15N.
This procedure provides an absolute quantitation of the amount of CCR5 mRNA in a given tissue.
Unfortunately, preamplification introduces unpredictable bias in the relative amplitude of different genes, prohibiting absolute quantitation of the original mRNAs.
The method of standard addition permits absolute quantitation of the physiologically active neuropeptide cerebrin from small structures, including nerves and neuronal clusters, in the femtomole range with a limit of detection of 19 fmol.
Absolute quantitation of the levels of modified bases at a specific restriction site can be obtained by using two restriction enzymes that cleave at the same site, but where only one can cleave in the presence of a specific DNA base modification.
In experiments to achieve absolute quantitation of the cerebrin in a small region of the cerebral commissure, ∼1/10 of this structure was dissected and placed onto a sample plate and covered with 500 nL of CHCA matrix containing the internal standard angiotensin I.
Therefore, studies involving absolute quantitation of these proteins are needed to investigate further the observed trends in type II cohesion-dockerin ratios, which would also provide insight into the plasticity or elasticity of the cellulosome complex.
For absolute quantitation of peptides in the F- and C-clusters and in the ULAB nerves, peptides from the cell(s) or tissue were extracted using the acidified methanol solution.
The absolute quantitation of HMOs is challenging due to the lack of standards and the difficulty in achieving complete chromatographic resolution of individual structures.
Absolute quantitation of mRNA concentration in the original sample was achieved using a standard curve generated for each batch [ 54].
The ddPCR (droplet digital PCR) is a highly sensitive recently developed technology 13, enables the absolute quantitation of nucleic acids in a sample and allows the detection of rare mutant alleles and the identification of mutational status of a patient's cancer after assessment of circulating tumor DNA (ctDNA) in cell-free plasma 14.
