Recommended Assay Procedures

ELISA:  The purified MP2-8F8 antibody (Cat. No. 554381) is useful for measuring mouse IL-3 protein levels when utilized as a capture antibody in sandwich ELISA. Purified MP2-8F8 antibody can be paired with the biotinylated MP2-43D11 antibody (Cat. No. 554384) as the detecting antibody, with recombinant mouse IL-3 (Cat. No. 554579) as the standard. Purified MP2-8F8 antibody should be titrated 2-6 µg/mL to determine the optimal concentration for ELISA capture. To obtain linear standard curves, doubling dilutions of mouse IL-3 (Cat. No. 554579), ranging from ~2000 to 15 pg/mL, are recommended for inclusion in each ELISA plate.  When measuring mouse IL-3 in serum or plasma, investigators are encouraged to utilize BD OptEIA™ Mouse IL-3 Set (Cat. No. 555228).

Note: This ELISA pair has been reported to show no cross-reactivity with the following the cytokines:

Mouse IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-9, IL-10, IL-12 p70, IL-15, GM-CSF, IFN-γ, MCP-1, TCA-3, TNF

Human IL-1α, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12 p70, IL-12 p40, IL-13, IL-15, G-CSF, GM-CSF, IFN-γ, lymphotactin, MCP-1, MCP-2, MIP-1α, MIP-1β, NT-3, PDGF-AA, sCD23, SCF, TNF, LT-α, VEGF; rat IL-2, IL-4, IL-6, IL-10, GM-CSF, IFN-γ, TNF).

Neutralization:  The NA/LE™ MP2-8F8 antibody (Cat. No. 554379) has been reported to be useful for neutralization of mouse IL-3 bioactivity.

Flow cytometric analysis and blocking control for intracellular staining:  The MP2-8F8 antibody is useful for flow cytometric analysis in identifying and enumerating IL-3 producing cells within mixed cell populations. PE-conjugated MP2-8F8 antibody (Cat. No. 554383) is especially suitable for these studies.  In addition, purified MP2-8F8 antibody can be used as a blocking control to demonstrate specificity of IL-3 staining by PE-conjugated MP2-8F8 antibody. To perform this control, the fixed/permeabilized cells (~1 million) can be incubated with 1 - 10 µg of unlabeled MP2-8F8 antibody (Cat. No. 554381) for 20 minutes at 4°C, prior to staining with PE-MP2-8F8. The intracellular cytokine staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  3. Please refer to for technical protocols.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
