Curve from a sandwich ELISA that measures IL-9 protein levels. It was generated using the purified MH9A4 antibody as capture antibody, doubling dilutions of recombinant human IL-9 protein as standard and biotinylated MH9A3 antibody as detection antibody. Avidin-HRP and the TMB substrate were used to develop the detection stage and mean OD was measured at 450 - 570 nm. The standard curve is displayed as the concentration of recombinant human IL-9 in pg/ml versus the microwell absorbance (in circles).

Preparation And Storage
Recommended Assay Procedures
This antibody is useful as a capture antibody in ELISA assays measuring human IL-9 protein levels. This antibody is non-blocking, it does not block the binding of IL-9 with the IL-9 receptor. The MH9A4 mAb can be used as a capture antibody in a sandwich ELISA with Biotinylated MH9A3 anti-human IL-9 protein (Cat. No. 558089) as the detector antibody, with recombinant human IL-9 protein as the standard. The MH9A4 antibody should be titrated between 1-4 µg/ml to determine its optimal ELISA coating concentration. To obtain linear standard curves, doubling dilutions of the recombinant human IL-9 protein ranging from 1.0 to 125 pg/ml are recommended for inclusion in each ELISA plate. For specific methodology, see https://www.bdbiosciences.com/en-us/resources/protocols/cytokine-elisa.
Note: This ELISA antibody pair shows no crossreactivity with the following recombinant human cytokines: IL-1α, IL-1β, IL-2, IL-3, IL-4, IL5, IL-6, IL-7, IL-8, IL-10, IL-12p40, IL-12p70, IL-13, IL-18, IFNγ, gp130, TNF, 4-1BB. This ELISA antibody pair also shows no cross-reactivity with recombinant mouse IL-9.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

The MH9A4 monoclonal antibody reacts with human interleukin-9 (IL-9), 14.1 kDa T cell-derived multifunctional cytokine . IL-9 induces the proliferation and differentiation of various lymphoid (eg, T lymphocytes, B lymphocytes, mast cells, eosinophils, and neutrophils) and hemopoietic cells, It potentiates the interleukin-4-induced IgG and IgE responses by human B lymphocytes. Further, IL-9 has been implicated in human allergic disorders.
