CENTA

CENTA is a colorimetric cephalosporin substrate for beta-lactamases. Upon hydrolysis by beta-lacatamases, CENTA turns from light yellow to chrome yellow, which can be quantified by colorimetric detection at 405 nm as a measure of beta-lactamase activity.Formal Name: (6R,7R)-3-[[(3-carboxy-4-nitrophenyl)thio]methyl]-8-oxo-7-[[2-(2-thienyl)acetyl]amino]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid.
