Tetracyclines In Honey

Tetracyclines In Honey LC-MS/MS Analysis Kit

Tetracyclines (TCs) are broad-spectrum antibiotics, widely used in animal husbandry and apiculture for prevention and treatment of diseases and as growth promotion.

Antibiotics are found in honey largely because they are used in apiculture for treatment of bacterial diseases. Oxytetracycline is commonly used to treat European foulbrood disease (EFB) and American foulbrood diseases (AFB) caused by Paenibacilus (Bacillus) larvae and Streptococcus pluton bacteria, respectively.

Highlights

Easy sample preparation without the need for solid phase extraction (SPE) and additional concentration steps

Shorter run time.
