  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

IL9R / CD129 antibody was raised against sf21-derived rhIL-9 R extracellular domain.
Extracellular Domain
Recognizes human IL-9R. In direct ELISAs, this antibody does not cross-react with rhIL-4 R, rhIL-5 R, rhIL-5 R, rhIL-13 R 1, rhIL-13 R 2, or rmIL-9 R.
Neutralization of bioactivity, Flow Cytometry, Direct ELISA. Neutralization of Human IL-9 Receptor-mediated bioactivity: The exact concentration of antibody required to neutralize the human cell surface IL-9 R mediated bioactivity is dependent on the IL-2 concentration as well as on the number and types of IL-2 receptors present on the cell surface (a function of cell type and culture conditions). The Neutralization Dose50 (ND50) for this antibody is defined as that concentration of antibody required to yield one-half maximal inhibition of the cell surface IL-9 R mediated IL-9 response on a responsive cell line, at a specific IL-9 concentration. The ND50 for this lot of anti-human IL-9 R antibody was determined to be approximately 2-4 ug/mL for inhibiting the IL-9-dependent proliferation of MO7e cells (1 x 10^5 cells/mL) in the presence of 2 ng/mL of rhIL-9. Flow Cytometry: This antibody was validated for flow cytometry using blood-derived monocytes. Dilute this antibody to 50 ug/mL and add 10 ul of the diluted solution to 1-2.5 x 10^5 cells in a total reaction volume not exceeding 200ul. The binding of unlabeled antibodies may be visualized by adding a secondary developing reagent such as anti-mouse IgG conjugated to a fluorochrome. Direct ELISA: This antibody can be used at 0.5-1.0 ug/mL with the appropriate secondary reagents to detect human IL-9 R. The detection limit for rhIL-9 R is approximately 6 ng/well.


Lyophilized from PBS, 5% trehalose. Reconstitution: Reconstitute, sterile PBS. If 1 ml of PBS is used, the antibody concentration will be 500 ug/ml.

IL9R / CD129 is a cytokine receptor that specifically mediates the biological effects of interleukin 9 (IL9). The functional IL9 receptor complex requires this protein as well as the interleukin 2 receptor, gamma (IL2RG), a common gamma subunit shared by the receptors of many different cytokines. The ligand binding of this receptor leads to the activation of various JAK kinases and STAT proteins, which connect to different biologic responses.
