are used to produce bioluminescence in order to visualize cellular activities and to track cell populations in vivo.
The kinetic ans structural properties of different species of firefly luciferases
have been found different due to alteration in their 3-dimentional structures.
These creatures all owe their glow to an enzyme called luciferase
Promega Corporation announces the launch of a novel luciferase
that is smaller, brighter, and more versatile than any current bioluminescent enzyme.
The cloning and characterization of the novel luciferases
from these chaetognath species will be a fascinating glimpse into the evolution of coelenterazine-based bioluminescence.
Expression in Escherichia coli of biotinylated luciferases
using biotin acceptor peptides.
By linking various luciferase
genes to other genes of interest spliced into cells, scientists can now measure the relative activity rates of multiple genes in cells over time.
We are pleased to include Promega's recombinant firefly and humanized Renilla luciferases
as reporters in our product lines.
We have isolated three new molecular species of Periphylla luciferase
from the ovaries of Periphylla, and named them luciferases
A, B, and C, respectively.
The activity of luciferases
in catalyzing light emission, i.
is inactivated by the chemical reactions involved in direct labeling of antigens or antibodies (9).
