    Biological Activity: Proliferation is measured using NFS-60 indicator cells, Specific Activity: 0.5 - 5.0 x 10^9 Units/mg, ED50: 2 - 20 pg/ml
    Observed dose response: 80 fold.
    Note: A Unit is defined as the amount of material required to stimulate a half-maximal response cytokine saturation. Investigators are advised to determine optimal concentrations for individual applications.
    产品特性
    Recombinant mouse IL-3 is supplied as a frozen liquid comprised of 0.22 µm sterile-filtered aqueous buffered solution and containing glycerol and 2 mg/ml biotechnology grade, low endotoxin bovine serum albumin, with no preservatives. The recombinant mouse IL-3 was purified by immunoaffinity chromatography and was found to be > 95% pure by SDS-PAGE analysis, and an absorbance assay based on the Beers-Lambert law.

  • 应用备注
    ELISA Standard: This recombinant mouse IL-3 is useful as a quantitative standard for measuring mouse IL-3 protein levels in an IL-3 specific sandwich ELISA with the purified MP2-8F8 antibody (Cat. No. 554381) as a capture antibody and the biotinylated MP2-43D11 (Cat. No. 554384) as the detection antibody. To obtain linear standard curves, doubling dilutions of this mouse IL-3 standard from 1800-7.5 pg/ml should be included in each ELISA plate. For specific methodology please visit the protocol sections or the chapter on ELISA in the Immune Function Handbook, both of which are located on our web site, www.bdbiosciences.com.
    Note: This ELISA pair is recommended primarily for measuring cytokine from experimental cell culture systems. These ELISA reagents are not recommended for assay of serum or plasma samples. For measuring mouse IL-3 in serum or plasma the BD OptEIA™ Mouse IL-3 ELISA Set (Cat. No. 555228) is specially formulated and recommended.
    Ligand Blocking Control for Immunofluorescent Staining of Cytokines: The recombinant mouse IL-3 can be used as a blocking control to demonstrate specificity of IL-3 staining by the PE-labeled MP2-8F8 antibody (Cat. No. 554383). The intracellular cytokine staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe. For specific methodology please visit the protocol sections or the chapter on intracellular staining in the Immune Function Handbook, both of which are located on our web site, www.bdbiosciences.com. Please Note: This application is not routinely tested at BD Biosciences.

    注意事项
    Interleukin-3 (IL-3) is a species-specific cytokine which acts on hematopoietic progenitors of every lineage, with the probable exception of cells committed to the lymphoid lineage. It has been referred to as CSF-2 , BPA, megakaryocyte CSF, HCGF and hemopoietin 2. Mouse IL-3 is a 17.2 kD protein containing 140 amino acid residues.
