  Selectoprobe™ Europium Cryptate HTRF Labeling Reagent (Eu cryptate DBCO)

  Catalog No.: SP-F-0155

  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 Selectoprobe™ Eu DBCO (europium complex) can be readily clicked to molecules containing an azido group under copper-free conditions.

  Compared to the other compounds, our 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.

  Selectoprobe™ polyHRP-Streptavidin Conjugate

  Catalog No.: SP-F-0158

  Description: Immunoassays (such as histochemistry, ELISAs and Western blotting) are important in clinical diagnosis and experimental protein analysis. These indirect analytical strategies primarily rely on the binding of an antigen by a specific antibody (primary antibody), followed by the detection of primary antibody by an enzyme or fluorescently labelled secondary antibody, allowing the semi-quantitative detection of a protein of interest. Histochemistry, ELISAs and Western blotting have been the common choices for protein validation studies for the past several decades. Technical advancements and modifications are continuously being developed to enhance the detection sensitivity of these procedures. Among them, streptavidin-containing poly-horseradish peroxidase (PolyHRP) based detection strategies have been shown to improve signals in a variety of immunoassays. The commercially available streptavidin and antibodies conjugated with many HRPs (PolyHRPs) have been widely used to enhance the detection sensitivity in immunoassays.

  Selectoprobe™ polyHRP-Streptavidin Conjugate is compatible with chromogenic, fluorogenic and chemiluminescent HRP substrates used in ELISA, Western blotting, immunohistochemistry (IHC) and nucleic acid hybridization assays. Due to the extremely high sensitivity of Selectoprobe™ polyHRP-Streptavidin Conjugate a blocking procedure may been needed to eliminate the interference caused by the endogenous biotinylated proteins.
