- BIOLOGICAL ACTIVITY: The ED50 was determined by the dose - dependent stimulation of the proliferation of human TF - 1 cells is < 2.0 ng/mL, corresponding to a specific activity of > 5 x 105 units/mg.
Properties
- PURITY: Greater than 98% by SDS-PAGE gel and HPLC analyses.
Endotoxin level is less than 0.1 ng per μg (1EU/μg). - PHYSICAL STATE: Lyophilized
- STORAGE CONDITIONS: The lyophilized IL-5 recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted IL-5 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing IL-5 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background
- IL-5 is a hematopoietic growth factor that stimulates the proliferation and activation of eosinophils. Produced by mast cells, T cells, and eosinophils, IL-5 plays an important role in inducing cell-mediated immunity against parasitic infections and certain tumors. Elevated levels of IL-5 lead to Eosinophilia, which may result in the induction of asthma and other allergic diseases. Human and murine IL-5 is cross-species reactive. Recombinant murine IL-5 is a 26.2 kDa disulfide-linked homodimeric protein containing two 113 amino acid chains.
