    Product Information

    Product Description

    This Cell Signaling Technology® antibody is the trFluorTM Europium Cryptate version of the unconjugated HA-Tag (C29F4) Rabbit mAb #3724 and is expected to detect transfected cell lysate or recombinant proteins containing the HA tag. Time-resolved (TR) fluorescence resonance energy transfer (FRET), or TR-FRET, data were generated using the conjugated antibody.

    Fluorescent Properties

    • ← Excitation: 305 nm ← Emission: 617 nm

    Product Usage Information

    trFluor™ Europium Cryptate conjugated antibodies are ideal for protein-protein interaction assays, pair-based immunoassay technologies, or high-throughput screening where greater sensitivity and quantitative detection is needed. The long fluorescent decay time of Europium Cryptate results in improved signal to background over fluorescent dye conjugates. Methods utilizing Europium Cryptate conjugated antibodies include, but are not limited to, TR-FRET, where Europium Cryptate-labeled donor antibodies are paired with red fluorophore-labeled acceptor antibodies, such as Alexa Fluor® 647 or APC. Please contact us if you require an acceptor antibody clone conjugated to a red dye at a custom concentration, a carrier-free formulation, or a more customized packaging solution.
    Note: Addition of potassium fluoride (KF) in the assay dilution buffer range of 40-400 mM is recommended for enhanced fluorescent signal. Optimal dilutions and working concentrations of both the conjugated antibodies and the KF should be determined by the end user.

    Storage

    Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

    Specificity / Sensitivity

    HA-Tag (C29F4) Rabbit Monoclonal Antibody (trFluor™ Europium Cryptate Conjugate) detects exogenously expressed proteins containing the HA epitope tag.

    Species Reactivity:

    All Species Expected

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide containing the influenza hemagglutinin epitope (YPYDVPDYA).

    Background

    Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein’s biochemical properties.

    The HA tag is derived from an epitope of the influenza hemagglutinin protein which has been used extensively as a general epitope tag in expression vectors (1).
