Flamma® 749 ADIBO
Cat. No. List below
Description
The dye exhibits excitation and emission maxima at 749 nm and 774 nm, respectively, which places it in the NIR region of the spectrum. These spectral characteristics are similar to other well-known NIR dyes such as Alexa 750, Cy7, IRDye 750, and DyLight 755. Flamma 749 can be efficiently excited using a 750 nm laser line or dye-pumped laser, with emission occurring in the NIR region, making it particularly advantageous for biological tissue imaging due to improved penetration and reduced autofluorescence.
Flamma® Fluors 749 ADIBO participates in SPAAC reactions, coupling with azide-functionalized biomolecules to form 1,4-disubstituted 1,2,3-triazoles without the need for coupling reagents or catalysts. This unique feature allows for efficient labeling inside living systems while preserving native biochemical processes. To utilize this dye effectively, researchers must first introduce azide functionality onto the target biomolecule through chemical or genetic modification.
Flamma® Fluors 749 ADIBO is particularly useful for cellular imaging (provides stable fluorescence signals for various biological imaging applications), nucleotide functionalization (enables specific labeling of nucleic acids), bioconjugation (facilitates the attachment of the dye to various biomolecules through click chemistry), and in vivo imaging (the NIR properties make it suitable for deep tissue imaging without interfering with biological systems).
Flamma® Fluors 749 ADIBO advantages:
1. Reduced Background Fluorescence: The NIR properties minimize interference from biological samples.
2. Enhanced Tissue Penetration: Suitable for in vivo applications where deep tissue imaging is required.
3. Versatile Labeling Options: Can be used for a broad range of biomolecules once azide groups are introduced.
These features make Flamma® Fluors 749 ADIBO a valuable tool for researchers in molecular biology, biochemistry, and biomedical imaging. Its unique reactivity and spectral properties expand the toolkit available for bioconjugation and probe development, particularly in studying complex biological systems within living organisms.

Flamma® Fluors for Click Chemistry
The most widely utilized click chemistry is 1,3-dipolar cycloaddition between an azide and an alkyne to produce 1,4-disubstituted 1,2,3-triazole. There are two types of 1,3-dipolar cycloaddition methods: copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) and strain-promoted azide-alkyne cycloaddition (SPAAC). BioActs offers Flamma® Fluors Alkyne dyes for CuAAC, Flamma® Fluors ADIBO products for SPAAC and Flamma® Fluors Azide dyes for both CuAAC and SPAAC.
