25x Biotin-detection Ab (human IL-5 Biotin-dAb). PN: A111176TB. One vial containing 35 µL of biotinylated anti-human IL-5.

Lyophilized Standard Mix-Human Group 2 Panel A, 10-Plex. PN: HG2009A. One vial containing lyophilized recombinant human G-CSF, GM-CSF, IFNα2, IL-1α, IL-3, IL-5, IL-7, IL-11, IL-12p40, and IL-13. Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits. 

STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Interleukin 5 (Accession P05113) or Eosinophil Differentiation Factor (EDF) is produced by both hematopoietic and non-hematopoietic cells such as T cells and granulocytes. IL-5, along with IL-3, and GM-CSF are mediators for eosinophil differentiation, though IL-5 has an eosinophil specificity and plays a role in their maturation. Overexpression of IL-5 in vivo increases amounts of B cells (mostly in mice), eosinophils (in humans), and antibodies significantly. Targeting IL-5 expression may have implications for such conditions as food allergies, asthma, inflammatory bowel diseases, and drug hypersensitivity.
