6-TAMRA Cadaverine TFA salt

6-TAMRA Cadaverine TFA Salt

This product is a fluorescent probe composed of 6-carboxytetramethylrhodamine (6-TAMRA), a cadaverine linker, and a trifluoroacetate counterion. The 6-TAMRA dye provides bright orange-red fluorescence with excellent photostability, while the cadaverine moiety introduces a reactive primary amine for conjugation with carboxyls, NHS esters, or other electrophiles. The TFA salt form specifically improves solubility and handling, making this dye a reliable tool for labeling and imaging.

Key Features and Benefits

• 6-TAMRA Fluorophore: Emits strong orange-red fluorescence with sharp spectra.

• Cadaverine Amine: Reacts with carboxyl or activated esters to form stable conjugates.

• TFA Salt Form: Enhances solubility and stability during storage and use.

• Photostable Signal: Provides consistent, bright labeling for imaging applications.

• High Purity: Produced to ≥95% purity for reproducibility.

Applications

• Protein and Antibody Labeling: Conjugates to activated carboxyl groups for fluorescent tagging.

• Fluorescent Imaging: Offers bright, stable signals for microscopy and flow cytometry.

• Probe Development: Serves as a building block for fluorescent probes.

• Diagnostics: Useful in assay development and biosensing platforms.

Storage and Handling

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

• Handling: Avoid prolonged light exposure; prepare fresh solutions before use.

This product integrates bright 6-TAMRA fluorescence with amine reactivity in a stable salt form, making it especially effective for bioconjugation and imaging.
