5(6)-TAMRA Acid

5(6)-TAMRA Acid

This product is a carboxyl-functionalized rhodamine dye mixture (5- and 6-isomers). It specifically provides bright, photostable orange-red fluorescence for labeling, imaging, and probe development.

Key Features and Benefits

• Carboxyl Group: Enables conjugation to amines via carbodiimide or active ester chemistry.

• Bright Fluorescence: Excitation/emission ≈ 546/579 nm for strong signal intensity.

• Isomeric Mixture: Contains both 5- and 6-TAMRA positional isomers.

• Photostability: Provides reliable performance in microscopy and assays.

• High Purity: Ensures reproducibility in labeling and fluorescence studies.

Applications

• Bioconjugation: Labels peptides, proteins, and oligonucleotides through amide bonds.

• Probe Development: Builds fluorescent probes for diagnostics and imaging.

• Cell Imaging: Provides robust orange-red signal in live or fixed cells.

• Assay Development: Useful in ELISA, FRET, and fluorescence-based detection.

Storage and Handling

• Storage: Store at –20 °C in sealed, light-protected container.

• Handling: Dissolve in DMSO or DMF; avoid repeated freeze–thaw cycles.

This product integrates carboxyl reactivity with bright, photostable rhodamine fluorescence, making it an especially versatile probe for imaging and detection workflows.
