Description: The P450-Glo CYP450 Assays provide a homogeneous,
luminescent method for measuring cytochrome P450 activity. The assays are
designed to measure the activities of P450s from recombinant and native
sources and for testing the effects of analytes such as drugs and new chemical
entities on P450 activities. These luminescent assays exhibit exquisite
sensitivity, low background signals and broad dynamic range.
P450-Glo Assays employ luminogenic P450 substrates that are derivatives
of beetle luciferin. The derivatives are not substrates for luciferase but are
converted by P450s to luciferin, which in turn reacts with luciferase to produce
light that is directly proportional to the activity of the P450.
The P450-Glo Assays generate a “glow-type” luminescent signal, produced
using a recombinant stabilized luciferase (Ultra-Glo Luciferase) coupled with
a proprietary buffer system. The half-life of the luminescent output is greater
than two hours, eliminating the need for luminometers with injectors and
allowing batch plate processing. The formulation also minimizes the incidence
of false positives due to inhibition of luciferase by analytes when screening for
cytochrome P450 inhibitors.
The new P450-Glo CYP3A4 Assay with Luciferin-IPA contains a new
substrate for cytochrome 3A4 that is very well suited for all applications
involving human CYP3A4 and is the best substrate available for cell-based
applications. Luciferin-IPA is readily taken up by cells and rapidly converted into
luciferin inside the cell, which reduces the incubation time required. The low
background and high signal-to-noise ratio produced using Luciferin-IPA means
less starting material is required.
Dimethyl sulfoxide (DMSO) can inhibit the activity of the 3A4 isoform of cytochrome
P450, even at low concentrations (
