产品名称:
IL-9 Recombinant Protein
别名:
P40, Il-9, Interleukin-9, Cytokine P40, IL-9
表达系统:
E. coli
保存温度:
The lyophilized IL-9 recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted IL-9 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-9 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-9 is an immunoregulatory cytokine produced by IL-2 activated Th2 lymphocytes. IL-9 enhances the proliferation of T lymphocytes, mast cells, erthroid precursor cells and megakaryoblastic leukemia cell lines. Over-expression of IL-9 has been implicated in the pathogenesis of anaplastic lymphoma and Hodgkin's disease. Whereas murine IL-9 can function on human cells, human IL-9 is inactive on mouse cells. Recombinant murine IL-9 is a 14.3 kDa protein of 127 amino acid residues including 10 cysteine residues which are fully conserved between the human murine proteins.
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 proliferation of human MO7e cells is < 0.5 ng/mL, corresponding to a specific activity of > 2 x 106 units/mg.
