Production of complementary DNA representing hepatitis A viral sequences by recombinant DNA methods and uses therefor

摘要

Methods for producing HAV cDNA, products thereof, and uses thereof, are described. HAV cDNA is produced, for example, by reverse transcribing HAV RNA and subsequently inserting the HAV cDNA into bacterial plasmids by genetic-engineering techniques. Transformed bacteria are then cloned and cultured to produce replicated chimeric plasmids containing the HAV cDNA. Such HAV cDNA is useful in assaying for the presence of HAV and in the production of HAV antigen and in the production of antibodies against HAV.
