Sulfamethazine (SMZ) was first approved as an antibacterial drug in 1947 due to its ability to inhibit bacterial dihydropteroate synthase. SMZ belongs to a class of antibiotics called sulfonamides which are widely used in veterinary medicine and the livestock industry. This sulfamethazine—BSA conjugate HL is highly loaded with an average of 20 to 30 SMZ molecules per BSA and can be used for immunization or immunoassay development. Sulfamethazine is coupled to BSA via its surface amines. The final conjugate is supplied in a lyophilized form containing phosphate buffered saline (PBS) and sugar-based stabilizers. This process makes the conjugates more stable for storage and shipment.nnThe product is sold as either 1 vial of 1 mg (Cat# CM52136-1MG) or 5 vials of 1 mg (Cat# CM52136-5MG).
