  • Synonym
  • Source
    Streptavidin Protein-Cy3(STN-NC114) is expressed from E. coli cells.
    Predicted N-terminus: Met
  • Molecular Characterization

    This protein carries no "tag".

    The protein has a calculated MW of 13.8 kDa.

  • Conjugate


    Excitation Wavelength: 555 nm

    Emission Wavelength: 569 nm

  • Labeling
    The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with Cy3 using standard chemical labeling method. The residual Cy3 is removed by molecular sieve treatment during purification process.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please protect from light and avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
 Streptavidin FACS

5e5 of Anti-CD19 CAR-293 cells were stained with 100μL of 20 ug/mL Biotinylated Human CD19 (20-291) Protein, Fc,Avitag™, premium grade (Cat. No. CD9-H82F6) and negative control protein respectively, washed and then followed with 2.5 μg/mL of Streptavidin Protein-CY3 (Cat. No. STN-NC114) and analyzed with FACS. PE signal was used to evaluate the binding activity (QC tested).

  • Background
    Streptavidin is a 66KDa tetrameric protein purified from the bacterium Streptomyces avidinii, and exhibits high binding affinity to biotin. Each unit can bind one biotin. Horseradish peroxidase is metalloenzyme, a 44KDa glycoprotein. When incubate with substrates, it produces a coloured, fluorimetric, or luminescent derivatives, which can be detected and quantified. HRP conjugated Streptavidin is widely used for the detection and quantification of biotinylated proteins.
