BETA LACTAMASE TEST is a rapid test in strip for detecting the enzyme beta-lactamase which confers resistance to pencicillins and
cephalosporins in a wide variety of both Gram positive and Gram negative microorganisms.

KIT CONTENT

PRINCIPLE OF THE METHOD
Nitrocefin is a chromogenic cefalosporin (3-(2,4 dinitrostyrl)-6R, 7R)-7-(2 thienylacetamido)-ceph-3-em-4 carboxylic acid, E-isomer) which
rapidly turns from yellow to red as the amide bond in the beta-lactam ring is hydrolysed by beta-lactamases; it is sensitive to hydrolysis by
all known lactamases produced by Gram positive and Gram negative microorganisms.
