(DB-411103)
txRED is a bright orange-red fluorescent dye that is structurally identical to Texas Red-X™. With its high photostability and pH resistance, it has become one of the most widely used fluorophores in life sciences.
This version features an extra aminohexanoyl spacer ('X') between the fluorophore and its reactive group. This spacer separates the dye from the biomolecule, reducing steric hindrance and preventing fluorescence quenching. txRED is perfect for a variety of imaging applications, including confocal microscopy, flow cytometry (FACS), and labeling cell cultures and tissues.
txRED Carboxylic Acid is a non-reactive dye used as a reference standard or for labeling peptides and proteins. Its carboxyl group can be activated (e.g., sulfo-NHS, TFP) or modified via carbodiimide chemistry for conjugation to amino groups. It’s commonly used in solid-phase peptide synthesis with activators like HATU.
Package size
Key Parameters: Great brightness and pH stability with lower costs
Carboxylic Acid: Ideal as a reference standard or for further synthesis
Applications: Confocal Microscopy, Super Resolution Microscopy, Flow Cytometry (FACS), DNA/RNA microarrays, whole-animal imaging, cell cultures and tissue labeling.
Cost-effective protocol compatibility: Offers the exact same spectral properties and performance as standard Texas Red-X™ at a more accessible price. It serves as a direct, highly economical substitute for Alexa Fluor® 594 when extreme photostability is not strictly required.
Complete Compatibility – Can be used in any existing protocol that uses Texas Red-X™
