Bento Gonçalves 9090, Porto Alegre, RS 91540-000 Nested PCR is a modification of a polymerase chain reaction technique intended to reduce PCR product contamination due to the amplification of non-specific primer binding sites. Protocol for the nested PCR: In the year 1993, Kamolvarin and coworkers described the method for use of two sets of primers for increasing sensitivity and specificity of the PCR. Everything else can be thawed to room temperature. Nested primers will only prime any specific product generated in the primary PCR, thus maintaining PCR specificity. Although there are no standardized PCR protocols, nested PCR has so far been the method most often used for this purpose. MATERIALS AND METHODS Viruses The ILTV strains were the vaccine Laryngo-vac1 and inactivated strain Cover2, which were used as positive controls.
