  • Non-toxic solvent for chromogenic substrate solution and uses thereof
    Patent number: 9046495
    Abstract: The present invention relates to a non-toxic dipolar solvent for chromogenic substrate for detecting presence of lacZ gene and/or gene activity, which comprises a stabilizing amount of a solubilizing agent. The present invention also relates to a method for inducing lac operon in screening assay, comprising the step of contacting an agar plate with at least one essential oil in a concentration sufficient to induce the lac operon. The present invention further relates to a method for detecting the presence of bacteria, comprising the step of contacting an agar plate with at least one essential oil in a concentration sufficient to induce detection of the bacteria.
    Type: Grant
    Filed: August 5, 2013
    Date of Patent: June 2, 2015
    Assignee: Pierce Biotechnology, Inc.
    Inventors: Pierre Sévigny, Martina Bielefeld-Sévigny
