Bacterial Beta Lactamase Assay Kit 

 

Drug target and enzyme assays

 

 

 

Resistance to β-lactam antibiotics such as penicillins, cephalosporins, cephamycins and carbapenems are due to hydrolysis of the four-atom ring known as β-lactam by β-lactamases (penicillinase) produced by Gram-negative bacteria. Inhibition of β-lactamases prevents bacterial degradation of beta-lactam antibiotics. 

ProFoldin’s high throughput assay for β-lactamases is based on binding of the dye with the hydrolyzed β-lactam that generates fluorescence at 535 nm (excitation at 485 nm). The assay can be performed in a 384-well or 96-well plate format for tests of β-lactamase activities and throughput screening of inhibitors against β-lactamases.
