Scientific Data Images for Human IL‑5 Antibody

IL‑5 antibody in Human Peripheral Blood Lymphocytes by Immunocytochemistry (ICC).

IL‑5 in Human Peripheral Blood Lymphocytes.

IL‑5 was detected in immersion fixed human peripheral blood lymphocytes using Mouse Anti-Human IL‑5 Monoclonal Antibody (Catalog # MAB605) at 5 µg/mL for 3 hours at room temperature. Cells were stained (red) and counterstained (green). Specific labeling was localized to the cytoplasm of PBMCs. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Detection of IL-5 antibody in PMA and Ca2+ionomycin-treated Human PBMCs antibody by Flow Cytometry.

Detection of IL‑5 in PMA and Ca2+ionomycin-treated Human PBMCs by Flow Cytometry.

Human PBMCs, untreated (light orange filled histogram) or activated with 50 ng/mL PMA and 500 ng/mL Ca2+ionomycin for 5 hours (dark orange filled histogram), were stained with Human IL-5 Monoclonal Antibody (Catalog # MAB605) or isotype control antibody (Catalog # MAB002, open histogram), followed by Fluorescein-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0103B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: IL-5

Interleukin-5 (IL-5) is a secreted glycoprotein that belongs to the alpha -helical group of cytokines (1 ‑ 3). Unlike other family members, it is present as a covalently linked antiparallel dimer (4, 5). The cDNA for human IL-5 encodes a signal peptide and a 115 amino acid (aa) mature protein. Mature human IL-5 shares 70%, 70%, 62%, 71%, 70% and 66%, aa sequence identity with mouse, rat, canine, equine, feline and porcine IL-5, respectively and shows cross‑reactivity with mouse IL-5. IL-5 is primarily produced by CD4+ Th2 cells, but also by activated eosinophils, mast cells, EBV-transformed B cells, Reed-Sternberg cells in Hodgkin’s disease, and IL‑2‑stimulated invariant natural killer T cells (iNKT) (1 ‑ 3, 6 ‑ 8). IL-5 increases production and mobilization of eosinophils and CD34+ progenitors from the bone marrow and causes maturation of eosinophil precursors outside the bone marrow (1, 6, 9, 10). The receptor for human IL-5, mainly expressed by eosinophils, but also found on basophils and mast cells, consists of a unique ligand-binding subunit (IL-5 R alpha ) and a shared signal‑transducing subunit, beta c (3, 6, 11). IL-5 R alpha first binds IL-5 at low affinity, then associates with preformed beta c dimers, forming a high-affinity receptor (12). IL-5 also binds proteoglycans, potentially enhancing its activity (13). Soluble forms of IL-5 R alpha   antagonize IL-5 and can be found in vivo (10, 14). In humans, IL-5 primarily affects cells of the eosinophilic lineage, and promotes their differentiation, maturation, activation, migration and survival, while in mice IL-5 also enhances Ig class switching and release from B1 cells (1 ‑ 3, 9, 10, 15, 16). IL-5 also promotes differentiation of basophils and primes them for histamine and leukotriene release (17).
