AF532 PEG4 biotin conjugate

AF532 PEG4 biotin conjugate contains Alexa Fluor 532 fluorophore that is well excited by the common 532 nm laser.


  • Water soluble
  • High affinity
  • pH independent fluorescence from 4-10
  • Flexible PEG4 spacer arm


AF532 PEG4 biotin conjugate can be used for detecting and quantifying biotin binding sites of avidin, streptavidin or neutravidin. This reagent overcomes major shortcomings of commonly used Biotin-4-fluorescein, e.g., poor solubility in aqueous media and pH dependent absorbance and short wavelength emission.
