IL-5 is a homodimeric, disulphide-linked protein produced by T-cells. Monomeric human IL-5 is a 126 amino acid protein with a reported molecular weight of 26 kD for the homodimeric protein. Mouse and human IL-5 are approximately 70% identical. IL-5 has been shown to promote the growth of immature hematopoietic BFU-E progenitors, stimulate the activation and differentiation of eosinophils, and promote the generation of cytotoxic lymphocytes. The JES1-39D10 antibody can neutralize the bioactivity of natural or recombinant IL-5.Product Details

ELISA Detection, ELISPOT Detection
- Recommended Usage
Each lot of this antibody is quality control tested by ELISA assay. For use as an ELISA detection antibody, a concentration range of 0.25-1.0 µg/ml is recommended. To obtain a linear standard curve, serial dilutions of human IL-5 protein ranging from 250 to 1 pg/ml are recommended for each ELISA plate when paired with TRFK5 (Cat. # 504302). To obtain a linear standard curve, serial dilutions of human IL-5 protein ranging from 500 to 4 pg/ml are recommended for each ELISA plate when paired with JES1-39D10 (Cat. # 500902).
For use as an ELISPOT detection antibody, a concentration range of 1-4 µg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
ELISA1-3 or ELISPOT4-6 Detection: The purified JES1-5A10 antibody is useful as a capture antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with biotinylated JES1-39D10 (Cat. No. 501002) as the detection antibody. Each lot of this antibody is quality control tested by ELISA assay.
Neutralization1: The LEAF™ Purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for neutralization of human IL-5 bioactivity.
Additional reported applications (for the relevant formats) include: Western blotting, immunohistochemical staining8,9 of paraformaldehyde-fixed, saponin-treated frozen tissue sections, and immunocytochemistry.
Note: For testing human IL-5 in serum or plasma, BioLegend's ELISA Max™ Sets (Cat. No. 430401 & 430404) are specially developed and recommended.
