About FluoBolt™–Technology
DETECT THE UNDETECTABLE
FluoBolt™ Technology is based on a physical effect called “Metal Enhanced Fluorescence” which is generated by metal nano structures on the bottom of our microplates. The unique features of FluoBolt™ Technology enable us to develop direct fluorescence immunoassays with the following benefits:
• High Sensitivity
• Single-step Procedure
• No Washing Steps
• No Enzyme Substrate required
• Long-term Stable Signals
• No special instrumentation required

About FluoBolt™–NogginFIA-1701
Noggin is a secreted homo dimeric glycoprotein which predominantly binds to BMP-4 and BMP-2 and antagonizes their bioactivities by preventing binding to both Type I and Type II BMP receptors. The FluoBolt™ Noggin assay detects free bioactive, not BMP complexed human Noggin, which was shown by inhibiting the signal of Noggin in human serum with recombinant BMPs.
Noggin is an early developmental biology TGF-beta growth factor that is intrinsic to many tissue development processes and therefore profusely connected to many diseases states. Some of the most commonly investigated are related to bone and nervous system, but Noggin has recently been characterized as an early biomarker in non-alcoholic fatty liver disease (NAFLD).
