Which capability is listed as part of the Diagnostic Research sector?

• A. DNA sequencing
• B. Genetic screening
• C. Protein purification techniques
• D. Bioinformatics

Answer: (C)

Diagnostic Research centers on creating and validating tests that detect disease indicators. A key capability in this area is isolating and studying the specific proteins that serve as biomarkers. Protein purification techniques allow you to extract and purify a target protein from a mixture, which is essential for characterizing the protein, producing high-quality antibodies, and developing reliable diagnostic assays such as immunoassays. Having a purified protein enables accurate standards, assessment of assay specificity, and reproducible measurements, all of which are core to diagnostic test development. While DNA sequencing and genetic screening relate to genetic analysis and biomarkers at the DNA level, and bioinformatics focuses on data interpretation, the hands-on purification of proteins directly supports creating and validating diagnostic tests.
