Fluorescent Dye Tb-Streptavidin

  • Catalog # : U0312

  • Specification
  • Product Description:
  • Fluorescent Dye Tb with Streptavidin conjugate. Fluorescent Dye Tb is optimized for TR-FRET applications with large Stokes shifts and extremely long emission half-lives when compared to traditional fluorophores such as Alexa Fluor® or Cyanine dyes.
  • Recommend Usage:
  • Labeling via Streptavidin for fluorescence imaging and other fluorescence-based biochemical analysis. For most fluorescent streptavidin applications, a concentration of 1-20 g/mL is sufficient.
    The optimal working dilution should be determined by the end user.
  • Storage Buffer:
  • Water
  • Storage Instruction:
  • Store the product in desiccated environment at -20°C and avoid from light.
    Add ddH2O with 0.1% BSA into the vial to have 1 mg/mL stock solution. This reconstituted solution remains stable for 2 months when stored in the presence of 2 mM sodium azide and avoid from light at 4°C. For longer storage, divid the reconstituted solution into single-used aliquots, or add equal volume of glycerol without aliquoting, and avoid from light at -20°C.
  • Note:
  • Maximum Excitation/Emission wavelength: 330/544 nm
