ABSTRACT

Se demostró la eficacia de la enzima transcriptasa inversa SensiScript para obtener material genético útil en la secuenciación de ácido nucleico de VIH-1, a partir de sueros colectados entre 1989 y 1998 y conservados a temperatura subóptima. Con el empleo de la enzima SensiScript se obtuvo amplificación del ARN del VIH-1 en 86,5 % de las muestras estudiadas, comparado con 20 % al utilizar la enzima AMV-RT. En 13,5 % de las muestras no se obtuvo amplificación con ninguna de las 2 enzimas empleadas.


The efficiency of SensiScript reverse transciptase to obtain useful genetic material in the sequencing of the nucleic acid from HIV-1, starting from sera collected between 1989 and 1998 and kept at suboptimal temperatures, was proved. On using the SensiScript enzyme it was obtained an amplification of the RNA of the HIV-1 in 86.5 % of the studied samples, compared with 20 % on using the AMV-RT enzyme . No amplification was obtained in 13.5 % of the studied samples with any of the 2 enzymes used.
