The phrase "a pool of serum" is correct and usable in written English.
It can be used in contexts related to biology, medicine, or laboratory settings, typically referring to a collection of serum in a specific area or container.
Example: "The researcher observed a pool of serum in the centrifuge after the blood samples were processed."
Alternatives: "a collection of serum" or "a reservoir of serum".
No reactivity of BCAL2958 protein was observed when using a sample of a pool of serum from healthy individuals (Fig. 4).
In a previous work using an immunoproteomic approach with a pool of serum samples from Bcc-infected CF patients, Shinoy et al. (2013) observed that OmpA-like proteins were immunoreactive and were present in strains of B. cenocepacia and B. multivorans.
The IgG antibody titers of each serum sample was determined by ELISA and revealed that all the samples from CF patients infected with Bcc had IgG titers higher than 4300, while the sample of a pool of serum from healthy individuals presented IgG titers below the threshold (Fig. 4b).
Positive control was a pool of serum with known high antibody recognition to CS2.
Reactivity against brain antigens expressed by Indian patients and by the standard consisting of a pool of serum from Gabonese CM patients are shown in Figure 3A.
Intensities were adjusted between membranes by a standard, consisting of a pool of serum from Gabonese CM patients [23] that was replicated twice on each membrane.
The YF-positive control serum was a pool of 12 serum specimens obtained from individuals who did not have anti-dengue antibody and had been recently vaccinated with YF-17DD.
On each plate, a seven-point dilution of the positive control (a pool of six serum samples from patients known to have high serum IgG anti-apoA-1) was performed starting at 1 25 dilution.
Samples, a positive (a pool of hyperimmune serum collected from a malaria endemic area) and negative controls (serum from European malaria naïve volunteers) were added in duplicate to each plate.
Fig. 4 The OmpA-like BCAL2958 protein is immunoreactive with sera from CF patients infected with Bcc. a Western blotting of the purified recombinant protein BCAL2958 from B. cenocepacia J2315 probed with the Human serum samples SCF1, SCF2, SCF3 and SCF4 from CF patients infected with Bcc bacteria, or a pool of human serum sample from healthy donors SH.
A Pool of CM serum was constituted with samples from patients showing a high reactivity to brain antigens.
