Life Technologies has announced the launch of a new ELISA test for bluetongue virus (BTV) antibodies.

According to the company, studies have confirmed that the LSI VET Ruminant Bluetongue II-serum ELISA can detect antibodies to BTV in experimentally infected sheep after 6 days, and in cattle after 7-8 days - several days sooner than some other commercially available test kits, including the company's previous ELISA test which the new product has replaced.

Life Technologies asked the UK's Pirbright Institute, the European Union Reference Laboratory for BTV, to conduct a preliminary assessment of the new test. The new test was able to detect antibodies in all 24 BTV reference sera and BTV 26 held by Pirbright, and showed high sensitivity in a longitudinal study of experimentally infected animals.

The Pirbright study also demonstrated that the LSI VET Ruminant Bluetongue II-serum ELISA could detect BTV antibodies in cattle and sheep that had been vaccinated with an inactivated Bluetongue vaccine.

The new test was developed by Life Technologies Animal Health in its research laboratory near Lyon in France and will be available in EU countries via Life Technologies Animal Health distributors according to local regulatory requirements (see www.lifetechnologies.com/lsi-animal-health) for details.
