Sulfanilamide is an organic sulfur compound structurally similar to p-aminobenzoic acid (PABA) with antibacterial property. Sulfanilamide competes with PABA for the bacterial enzyme dihydropteroate synthase, thereby preventing the incorporation of PABA into dihydrofolic acid, the immediate precursor of folic acid. This leads to an inhibition of bacterial folic acid synthesis and de novo synthesis of purines and pyrimidines, ultimately resulting in cell growth arrest and cell death.
CDIATM Sulfanilamides Test Kit is based on competitive indirect colloid gold immunochromatography technology, in which sulfanilamides in sample competes for the colloid gold labeled antibody with sulfanilamides coupling antigen captured on test line. The test result can be observed by naked eye.
