Intended use:

A competitive enzyme immunoassay for screening and quantitative analysis of cefalexin in various matrices.

General information:

Cephalosporins are bactericidal beta-lactam antibiotics and have the same mode of action as other beta-lactam antibiotics such as penicillins. Cefalexin is a first generation cephalosporin which is used for infections caused by gram-positive bacteria. The EU has set MRLs for cefalexin: 100 μg/kg in bovine milk, 200 μg/kg in bovine muscle, fat and liver and 1000 μg/kg in bovine kidney.
