产品名称:
IL-5 Recombinant Protein
别名:
EDF, TRF, IL-5, Interleukin-5, B-cell differentiation factor I
表达系统:
E. coli
保存温度:
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.

功能与背景:
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.
纯度:
Greater than 98% by SDS-PAGE gel and HPLC analyses.
Endotoxin level is less than 0.1 ng per μg (1EU/μg).
Endotoxin level is less than 0.1 ng per μg (1EU/μg).
生物活性:
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.
