In the present study reverse transcriptase (RT) polymerase chain reaction (PCR) products were generated from the RNA of polio virus. The products of the RT-PCR were analyzed by slab-gel electrophoresis (SGE) on 4% agarose gels, and capillary electrophoresis (CE). CE separations were performed in a coated capillary containing a linear polyacrylamide. Samples were injected hydrodynamically or electrokinetically. Detection of the RT-PCR products on CE was by UV absorbance at (254 nm) or by laser-induced fluorescence (LIF). While SGE resulted in adequate separation of 163 and 97 base pair RT-PCR products, separation of the 97, 71 and 53 base pair products was minimal. CE separations showed baseline resolution for all the above PCR products. Finally, it was possible to quantitate the amount of RT-PCR product by developing a standard curve showing a linear relationship between the amount of RNA used in the RT-PCR and the amount of product formed in the RT-PCR. These results suggest the greater resolution and enhanced sensitivity observed, together with the ease of quantitation, make CE a powerful alternative to SGE for the separation and quantitation of PCR products.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D017955	Poliovirus	A species of ENTEROVIRUS which is the causal agent of POLIOMYELITIS in humans. Three serotypes (strains) exist. Transmission is by the fecal-oral route, pharyngeal secretions, or mechanical vector (flies). Vaccines with both inactivated and live attenuated virus have proven effective in immunizing against the infection.
