The phrase "a donor sample" is correct and usable in written English.
It can be used in contexts related to medical, scientific, or research fields where a sample is provided by a donor for analysis or testing.
Example: "The laboratory requires a donor sample to conduct the necessary tests for compatibility."
Alternatives: "a sample from a donor" or "a specimen provided by a donor."
Gene expression analysis of T-cell activation at a single timepoint has been reported [ 8, 9], and using a single donor sample, the gene expression patterns of T-cell activation with or without co-stimulation by anti-CD28 antibody were compared [ 10, 11].
(G) Thymidine kinase 1 activity in fractions from the serum of a blood donor (Sample 17).
LHP is more frequently encountered in the mtDNA CR than PHP and refers to the presence of multiple length variants in a single donor sample.
These experiments were repeated using serum samples from one additional MDS (sample no. 15), breast cancer (sample no. 20) and prostate cancer (sample no. 27) patient and a blood donor (sample no.
Since our previous observations suggested quantitative differences in the predisposition of NK cells from individual anonymous donors to respond to mycobacteria, we evaluated this variability in a larger donor sample size.
The finite lifespan of primary HRBECs limits the number of cells available from a single donor sample for analysis and thus limits the number of repetitions of any assay.
Plastic adherent colonies were observed in all donor samples after 7 to 10 days.
For insertions and deletions, we define these relative to the reference genome: an insertion indicates the presence of a segment in the donor sample that is not in the reference.
To screen normal donors for Chlamydia carriage in circulating PBMCs, and to assess infectivity, we utilized ELISA, immunofluorescence microscopy, in vitro culture and flow cytometry A random cohort of blood donor sample residuals was obtained from the Blood Bank unit at Baystate Medical Center over a 12 month period.
Finally, we subjected the third, parallelpiped specimen (nominal dimensions of 2 mm×5 mm×40 mm) from each donor sample to a three point bending test, and measured four mechanical properties relevant to fracture risk in bone: yield stress, peak stress, flexural modulus, and pre-yield or elastic toughness.
