MaxSignal Beta-Lactam ELISA 


  • High sensitivity - Detects 0.8 ppb of beta-lactams in milk, meat, tissue, fish, urine and plasma
  • Detects a broad spectrum of beta-lactam antibiotics including cephalosporins
  • High recovery rates
  • Low-cost rapid, 10 minutes - 1 hour sample prep protocol
  • Rapid assay protocol - Less than 2 hours to process 40 samples in duplicate
  • High reproducibility (interplate and intraplate CV typically <8%)

The MaxSignal® Beta-Lactam ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of a broad range of beta-lactam antibiotics including ampicillin, penicillin G, amoxicillin, cloxacillin, oxacillin and cephalosporins (i.e. cefoperazone, ceftiofur, etc) in milk, meat, tissue, fish, urine, and plasma samples. 

Beta-lactam antibiotics are among the most widely used antibiotics for the treatment of bacterial infections in man and animals. Beta-lactams are also administered to animals in feed for growth promotion and for prophylactic treatment. The monitoring of beta-lactam residues in meat and milk is important because of the hypersensitivity of some individuals to these antibiotics and also the emergence of antibiotic-resistant strains of bacteria. For this reason, maximum residue limits have been specified for food products and milk to try and control the levels of these antibiotics reaching the consumer. With a detection limit of 0.8 ppb for most sample types, the MaxSignal® Beta-Lactam ELISA Test Kit allows for the accurate detection of beta-lactams at or below these maximum residue limits.

This kit is manufactured to the international quality standard ISO 9001:2008.
