The Kernel Ceftiofur ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of Ceftiofur in milk, urine, tissue (liver, kidney, and muscle), serum, and plasma samples. 

Ceftiofur is widely used to treat bacterial infections in man and animals. The monitoring of Ceftiofur residues in edible tissues and milk is important because of the hypersensitivity of some individuals to it 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 Ceftiofur reaching the consumer.
