For detection of carbapenemase-producing Enterobacteriaceae (CPE)

BBL CHROMagar ESBL biplate is a chromogenic selective screening medium for the detection of Enterobacteriaceae-producing, extended-spectrum beta-lactamases (ESBLs):

Technical Advantage:  Effective against Gram-positive and -negative Bacteria, and mycoplasma Gentamicin works as an antimicrobial agent by binding to the 30S ribosomal subunit of certain bacteria.  It is formulated to contain 50 mg/ml gentamicin in deionized water and is recommended for use in cell culture applications at 1 ml/L.  This product is effective against mycoplasma, Gram-negative and Gram-positive bacteria and is st…

IPTG (Isopropyl-beta-D-thiogalactoside) is an inducer of the lac operon and is frequently used in conjunction with X-GAL to determine the lac phenotype of recombinant plasmids or phage. IPTG is also used to induce the expression of cloned genes that are under control of the lac operon.

X-GAL (5-Bromo-4-Chloro-3 Indolyl-Beta-D-thiogalactopyranoside) is a chromogenic substrate for Beta-galactosidase that turns blue upon hydrolysis and is regularly used for the blue/white color selection assay. Bacteria with a lac+ phenotype grow as blue colonies on plates containing X-GAL.
