N-Methylmesoporphyrin IX
Based on 8 publication(s) in Google Scholar
N-Methylmesoporphyrin IX (NMM), a widely used G-quadruplex DNA specific fluorescent binder, is an efficient probe for monitoring Aβ fibrillation. N-Methylmesoporphyrin IX is an in situ inhibitor and an ex situ monitor for Aβ amyloidogenesis both in vitro and in cells. N-Methylmesoporphyrin IX is sensitive to G-quadruplexes DNA but has no response to duplexes, triplexes and single-stranded forms DNA. N-Methylmesoporphyrin IX is nonfluorescent alone or in monomeric Aβ environments, but emits strong fluorescence through stacking with the Aβ assemblies.

Descripciòn
In Vitro
Guide (The following is our recommended protocol; this is a guideline and should be modified according to your specific needs).
1. Preparation of Aβ peptide fibrils.
2. N-Methylmesoporphyrin IX (NMM) (10 μM) is co-incubated with Aβ peptide (50 μM) for 7 days at 37°C.
3. Additional N-Methylmesoporphyrin IX is added before fluorescence measurements to maintain a constant N-Methylmesoporphyrin IX concentration (1 μM).
4. Observed using a fluorescence microscope or flow cytometry (Ex/Em = 399/610 nm).
N-Methylmesoporphyrin IX (NMM) is sensitive to G-quadruplexes DNA but has no response to duplexes, triplexes and single-stranded forms DNA. Upon binding to quadruplex DNA, for efficient π-π stacking, NMM can adjust its macrocycle geometry to match the terminal face of a G-quadruplex, leading to an enhancement in its fluorescence[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
