Caption:
This image depicted a Centers for Disease Control and Prevention (CDC) scientist interacting with her Caliper LifeSciences’ Zephyr Molecular Biology Workstation, working with samples to be tested using a real-time PCR machine, known as a themocycler (see PHIL 22904), in order to identify the various types of poliovirus contained therein. The data from this analysis is stored in a computer, while the software further analyzes the data before being reviewed by a scientist. The themocycler can vary the temperature, which is important, for PCR requires multiple test rounds at different temperatures. In the instrument, viral RNA is copied into DNA and then the DNA is amplified. Specific probes bind to the DNA, in order to determine what type of polio present. One hundred ten labs around the world can run this assay, and can tell if an isolate contains polio, or not, and if so, what kind.
