  Selectoprobe™ Eu donkey anti-goat IgG (H+L) (Cross Adsorbed)

  Catalog No.: SP-F-0154

  Description: The Selectoprobe™ Eu probe enable time-resolved fluorometry (TRF) for the assays that require high sensitivity, showing large Stokes shifts and extremely long emission half-lives when compared to more traditional fluorophores such as Alexa Fluor or cyanine dyes. Compared to the other TRF compounds, Selectoprobe™ Eu probes have relatively high stability, high emission yield and ability to be linked to biomolecules.

  This lyophilized Selectoprobe™ Eu donkey anti-goat IgG (H+L) conjugate (Cross Adsorbed) is commonly used as a second step reagent for indirect immunofluorescent staining, when used in conjunction with primary antibodies.
