The phrase "serum composition" is correct and usable in written English.
It can be used in contexts related to biology, medicine, or chemistry, particularly when discussing the components or formulation of a serum.
Example: "The serum composition includes various proteins, electrolytes, and vitamins essential for cellular function."
Alternatives: "serum formulation" or "serum ingredients."
The serum composition of fatty acids was determined using the method by Lepage and Roy [24].
That is, there was a gradual dose-dependent shift of the absorbance peak to the right, reflecting probably a major change in serum composition (Fig. 2A).
The full serum composition is given in the "In vivo study" section.
Native human serum is the most commutable matrix among different laboratory methods because it mimics the entire serum composition [ 6].
It is also well described that serum composition can change over time [ 12, 13], which suggests that serum properties also change during long-term storage.
Clearly, the serum composition of GBM patients should be further studied as it may non-invasively provide highly valuable prognostic information for treating GBM beyond the current paradigms.
It is further expected that curcuminoids solubilized in sera from different species or possibly different preparations from the same species, will produce different apparent cellular binding KDs due to their variable serum compositions.
Thus, the changes in serum NEFA composition could reflect the VLDL composition in the HF group cats.
To evaluate changes in systemic BA regulation, serum BA composition was determined by liquid chromatography-mass spectrometry (Fig. 1C).
Analysis of serum cytokine composition was performed with RayBio Human Cytokine Antibody Array C Series 2000 (RayBiotech, Norcross, GA, USA) according to the manufacturer's instructions.
The plethora of information in urine makes it an attractive source for biomarker screening since, compared to serum, the composition of urine is relatively simple, and urine collection is easier and noninvasive [7], [8].
