Selectoprobeâ„¢ Europium Cryptate HTRF Labeling Reagent (Eu cryptate NHS ester)
Catalog No.: SP-F-0148
Description: The Europium cryptate labeling reagent is specifically designed for biomolecule labeling, enabling the rapid and efficient development of time-resolved fluorescence resonance energy transfer (TR-FRET) assays. It facilitates quick and easy labeling of peptides, proteins, and oligonucleotides.
The N-hydroxysuccinimide (NHS)-activated Europium cryptate reacts with the primary amines on biomolecules, allowing for simplified and efficient conjugation.
Compared to the other compounds, our Selectoprobeâ„¢ Cryptate Eu probes have extremely high stability, high emission yield and ability to selectively label biomolecules. Moreover, our Eu probes are insensitive to fluorescence quenching when conjugated to biological polymers such as antibodies.

Selectoprobeâ„¢ Eu-streptavidin conjugate
Catalog No.: SP-F-0149
Description: This lyophilized Selectoprobeâ„¢ Eu-streptavidin conjugate comprises streptavidin (as the biotin-binding protein) with Selectoprobeâ„¢ Eu covalently attached (as the time-resolved red fluorescent europium label). It is commonly used as a second step reagent for indirect immunofluorescent staining, when used in conjunction with biotinylated primary antibodies. It is a very valuable tool for biotin-streptavidin-based biological assays and tests using TR-FRET platform. A variety of the complementary biotinylated reagents are available from Selectoprobeâ„¢.

Selectoprobeâ„¢ Eu goat anti-mouse IgG (H+L) (Cross Adsorbed Antibody)
Catalog No.: SP-F-0153
Description: The Selectoprobeâ„¢ 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, Selectoprobeâ„¢ Eu probes have relatively high stability, high emission yield and ability to be linked to biomolecules. This lyophilized Selectoprobeâ„¢ Eu goat anti-mouse IgG (H+L) conjugate (Cross Adsorbed Antibody) is commonly used as a second step reagent for indirect immunofluorescent staining, when used in conjunction with primary antibodies.
