    Product Information

    Product Description

    This Cell Signaling Technology® antibody is conjugated to mFluor™ Red 780 fluorescent dye under optimal conditions and formulated at 200 µg/mL. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated #4814

    Fluorescent Properties

    • ← Excitation: 629 nm ← Emission: 767 nm

    Product Usage Information

    SignalFlex™ conjugates are produced using highly validated Cell Signaling Technology® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays.

    Optimal dilutions/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate.

    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

    IκBα (L35A5) Mouse mAb (Amino-terminal Antigen) (SignalFlex™ mFluor™ Red 780 Conjugate) detects endogenous levels of total IκBα protein.

    Species Reactivity:

    Human, Mouse, Rat, Monkey, Bovine, Pig

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a GST-IκBα fusion protein corresponding to the amino terminus of human IκBα.

    Background

    The NF-κB/Rel transcription factors are present in the cytosol in an inactive state complexed with the inhibitory IκB proteins (1-3). Activation occurs via phosphorylation of IκBα at Ser32 and Ser36 followed by proteasome-mediated degradation that results in the release and nuclear translocation of active NF-κB (3-7). IκBα phosphorylation and resulting Rel-dependent transcription are activated by a highly diverse group of extracellular signals including inflammatory cytokines, growth factors, and chemokines. Kinases that phosphorylate IκB at these activating sites have been identified (8).
