Application Notes

This antibody can effectively block IL-5 induced HL-60 histamine content and TF-1 proliferation. 39D10 was also evaluated for its ability to neutralize the ILJ-dependent growth of eosinophilbasophil colonies (i.e., both histamine-positive and histaminenegative Eo-type) in methylcellulose culture. This antibody did not cross-react with mouse IL-5 in indirect ELISA (PMID: 1706953). This antibody was used in immunohistochemical method to study the localisation and phenotype of individual cytokine producing cells in synovial biopsy specimens in rheumatoid arthritis (PMID:7677442). This antibody was also used in immunocytochemical and a flow cytofluorimetric method to detect intracellular IFN-g, IL-4 and IL-5 in T-cell clones, peripheral blood mononuclear cells PBMC and bronchoalveolar lavage fluid BALF cells (PMID: 9134033). The original rat IgG2a antibody binds human IL-5 with a binding affinity of Kd= 53 pM (PMID: 7613159). This antibody can be used in combination with JES1-5A10 for the detection of cytokines in a capture ELISA (PMID: 16827896). Humanized version of this antibody CMX5-2 and CMX5-5 had lower affinities for IL-5 than 39D10, with Kd values that were 1.4 times the Kd for 39D10 (PMID: 8844835).

Short Description

This chimeric human antibody was made using the variable domain sequences of the original Rat IgG2a format, for improved compatibility with existing reagents, assays and techniques.
