TAMRA ADIBO

Cat. No. List below

Description

TAMRA ADIBO is a versatile strain-promoted azide-alkyne cycloaddition (SPAAC) reagent that generates a stable, bright yellow fluorescence signal for bioimaging applications. This copper-free click chemistry-compatible fluorophore offers excellent optical properties and is widely used in cellular imaging and nucleotide functionalization.

Key Features:
1. Bright yellow-orange fluorescence
2. Excitation/Emission maxima: 543/575 nm
3. Extinction coefficient: ≥ 36,000 cm?¹M?¹
4. Molecular Weight: 690.8 g/mol
5. Appearance: Red solid
6. Solubility: DMF
7. Storage: -20°C, protected from light

Applications:
1. Cellular imaging
2. Nucleotide functionalization
3. Protein labeling
4. Biomolecule tracking in living systems
5. Flow cytometry
6. Fluorescence microscopy
7. Single-molecule detection

Advantages:
1. Efficient excitation with 543 or 546 nm laser lines
2. Spectrally similar to popular dyes like DyLight 549, ATTO 550, and Cy3
3. Forms stable 1,4-disubstituted 1,2,3-triazole linkages
4. Minimal interference with native biochemical processes
5. Bioorthogonal labeling strategy
6. High specificity and efficiency in click reactions
7. Versatile labeling of azide-modified biomolecules
8. Compatible with complex biological samples
9. Suitable for in vivo applications due to copper-free chemistry

TAMRA ADIBO couples with azide-functionalized biomolecules through strain-promoted azide-alkyne cycloaddition, forming a stable 1,4-disubstituted 1,2,3-triazole linkage. This reaction occurs efficiently inside living systems without the need for coupling reagents or catalysts, making it ideal for in vivo applications. To utilize TAMRA ADIBO, researchers must first introduce azide functionality onto the target biomolecule through chemical or genetic modification.

The SPAAC approach offers several advantages over traditional labeling methods and copper-catalyzed click chemistry. It provides high specificity, efficiency, and bioorthogonality, allowing for sensitive detection in complex biological samples with minimal background signal. The reaction proceeds under physiological conditions without the need for potentially toxic copper catalysts, making it highly suitable for live-cell imaging and in vivo studies.

Background

Other Labeling Dyes

BioActs provides other traditionally used dyes such as 5(6)-Carboxyfluorescein (FAM) and 5(6)-Carboxytetramethylrhodamine (TAMRA) dyes for labeling of biomolecules. FAM is one of popular green fluorescent reagents used for labeling peptides, proteins and nucleotides. In addition to relatively high absorptivity, good fluorescence quantum yield and good water solubility, FAM has an excitation maximum that closely matches the 488 nm spectral line of the argon-ion laser. TAMRA fluorophore has been a widely used for preparing bioconjugates, especially fluorescent antibody and avidin derivatives. TAMRA dye is also widely utilized for oligonucleotide labeling and automated DNA sequencing applications. TAMRA is often used as FRET acceptor for FAM fluorophore.

Other fluorescent dyes such as Cyanine, ICG, TAMRA, FAM, etc. are also available.
All dyes are equipped with various reactive and functional groups.
High quality and excellent performance
