IL-5/IL5/Interleukin 5 Neutralizing Antibody (Rabbit Monoclonal antibody) Validated Applications

ELISA(Det): This antibody will detect Human IL-5/IL5 / Interleukin 5 in ELISA pair set (Catalog: # SEKA15673). In a sandwich ELISA, it can be used as detection antibody when paired with (Catalog: # 15673-R001).
Block: In a functional ELISA which immobilized Human IL5 (Catalog#15673-HNCE) at 0.4 μg/mL (100 µL/well) in the plate, the Rabbit anti-Human IL5 Monoclonal Antibody (Catalog#15673-R013) can block the binding of 2 μg/mL  Human IL5R (Catalog#10392-H08H) to human IL5, the EC50 is 0.23 μg/mL.
Neutralization: The neutralization activity of IL5 neutralizing antibody is measured by its ability to neutralize IL5-induced proliferation in the TF‑1 human erythroleukemic cell line. The Neutralization Dose (ND50) is typically 2-8 ng/mL in the presence of 1.25 ng/mL Human IL5 (Catalog#15673-HNCE).
Please Note: Optimal concentrations/dilutions should be determined by the end user.

Cell Proliferation Induced by IL‑5 and Neutralization by Human IL5 Antibody. Human IL5 (Catalog#15673-HNCE ) stimulates proliferation in the TF‑1 human erythroleukemic cell line . Proliferation elicited by Recombinant Human IL5 (1.25 ng/mL) is neutralized by increasing concentrations of Rabbit Anti-Human IL‑5 Monoclonal Antibody (Catalog#15673-R013). The ND50 is typically 2-8 ng/mL .

IL-5 Background Information

Interleukin 5 (IL-5) is a member of the interleukin family with length of 115 amino acids. Interleukins are a group of cytokines (secreted proteins / signaling molecules) that were first seen to be expressed by white blood cells (leukocytes) and has been found in a wide variety of body cells. Interleukin 5 or IL-5 is produced by T helper-2 cells and mast cells. It helps to stimulate B cell growth and increase immunoglobulin secretion and is considered as a key mediator in eosinophil activation. Interleukin 5 (IL-5) has long been associated with several allergic diseases, including allergic rhinitis and asthma. Growth in the number of circulating, airway tissue, and induced sputum eosinophils have been observed in patients with these diseases. IL-5 also had something with the terminally differentiated granulocyte eosinophils. IL-5 was originally found as an eosinophil colony stimulating factor. It has been proved to be a major regulator of eosinophil accumulation in tissues, and can modulate eosinophil behavior at every stage from maturation to survival.
