  • Applikationshinweise
    ELISA Standard: Recombinant human IL-3 is useful as a quantitative standard for measuring human IL-3 protein levels in an IL-3 specific sandwich ELISA with the purified BVD8-3G11 antibody (Cat. No. 554672) as a capture antibody and the biotinylated BVD3-1F9 (Cat. No. 554674) as the detection antibody. To obtain linear standard curves, doubling dilutions of this human IL-3 standard from 2000 to 15 pg/ml should be included in each ELISA plate.
    Ligand Blocking Control for Immunofluorescent Staining of Cytokines: Recombinant human IL-3 can be used as a blocking control to demonstrate specificity of IL-3 staining by the directly conjugated-BVD3 1F9 antibody (Cat. No. 554676). 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 protocols section or chapter on intracellular staining in the Immune Function Handbook both of which are posted on our web site.
