Concept:Monoclonal antibodies (mAbs) are monospecific antibodies produced by identical immune cells (hybridomas) that bind specifically to one targeted epitope.
Solution:In diagnostic biotechnology, monoclonal antibodies are primary biological tools utilized to detect minute quantities of specific antigens or pathogens in patient clinical samples (such as blood, urine, or tissue samples) using assays like ELISA and rapid immunochromatographic tests.
Why other options are incorrect:- To stimulate white blood cell production: Colony-stimulating factors (CSFs) and specific cytokines carry out this physiological function, not monoclonal antibodies.
- To bind to toxins produced by pathogens: While neutralizing antitoxins can bind toxins therapeutically, this is not their primary diagnostic function.
- To label abnormal cells for immune destruction: This describes therapeutic monoclonal antibody mechanisms (like Antibody-Dependent Cellular Cytotoxicity) rather than diagnostic applications.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
