Mechanism of Action

CYTALUX® is a proprietary folic acid analog conjugated with a fluorescent dye which binds to folate receptor positive cells.

Certain cancers overexpress high-affinity folate receptors to increase folate uptake for tumor growth.1,2

Why Folate

Folate is an essential vitamin required for cell growth and DNA replication3

Rapidly dividing cancer cells requires an abundant supply of folate, therefore, it is consumed in elevated quantities3

How CYTALUX Works

CYTALUX is a small
molecule that
circulates quickly
through the body.
It can be infused
intravenously in as little as
an hour before imaging.
CYTALUX binds to the
folate receptors expressed
on cells.
It is targeted, preferentially
binding to FR+ cells.
CYTALUX is
endocytosed and
concentrates in folate
receptor positive (FR+)
ovarian and lung cancer
tissue.
Endocytosis allows it to be
concentrated in the tissues
throughout the entire
surgical procedure.
CYTALUX contains a
bright fluorophore which
is illuminated via
near-infrared light.
Imaging under near-infrared light
enhances intraoperative visualization
in challenging environments and
below the tissue surface.1
