(DB-411108)
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.
PEG4 spacer improves accessibility to binding partners in click chemistry and reduces nonspecific interactions with hydrophobic surfaces/proteins. It makes it better for in-cell labeling, protein conjugation, or any application where spatial flexibility, solubility, or reduced nonspecific binding is critical.
Package size
Key Parameters: Great brightness and pH stability with lower costs
PEG4-Azide: Improved reaction efficiency and reduced background
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™
