Tecna has released an ELISA test kit for the quantitative detection of antibiotic residues in food.

B Zero Strepto is designed for analysis of streptomycin and dihydrostreptomycin in honey, milk and animal tissues and takes 60 minutes.

The test kit has almost 100% cross-reactivity for streptomycin and dihydrostreptomycin - aminoglycoside antibiotic drugs.

Streptomycin is used to treat fruit-tree diseases and contamination of the blossom with high concentrations of antimicrobials implies risk of carry-over of residues into honey and royal jelly.

Measuring range for milk and honey is 2 - 400 ppb and 5 - 1000 ppb for muscle. The sensitivity of the assay was assessed as part of an in-house validation to EU Decision 2002/657.

It is an evolution from the I'screen Strepto enzyme immunoassay launched five years ago.

The B Zero format adopts a virtual calibration curve, the so called master curve, avoiding the need to run calibrations at each analytical session.

Common ELISA test kits require analysts to run a number of standards per session for calibration.

The B Zero portfolio includes ELISA test kits for quantitative detection of chloramphenicol, sulphonamides, tetracyclines and corticosteroids in different foodstuffs.
