(DB-410211)
AF 568 PEG5-Biotin is a bright orange-fluorescent dye that is structurally identical to Alexa Fluor 568. With its high photostability and pH resistance, it has become one of the most widely used fluorophores in life sciences. Its hydrophilic (much higher due to PEG) nature makes it an ideal choice for labeling sensitive proteins.
PEG5 spacer improves accesibility to binding partners. 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: High fluorescence quantum yield with lower costs
