IL9-218H
Optional Service: Optional requirements on this protein
Product Overview :
Recombinant Active Human IL9 Protein with His tag (N-ter) was expressed in E. coli.
Description :
The protein encoded by this gene is a cytokine that acts as a regulator of a variety of hematopoietic cells. This cytokine stimulates cell proliferation and prevents apoptosis. It functions through the interleukin 9 receptor (IL9R), which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. The gene encoding this cytokine has been identified as a candidate gene for asthma. Genetic studies on a mouse model of asthma demonstrated that this cytokine is a determining factor in the pathogenesis of bronchial hyperresponsiveness. [provided by RefSeq, Jul 2008]
Source :
E. coli
Species :
Human
Tag :
His(N-ter)
Form :
Powder
Bio-activity :
Determined by its ability to induce proliferation in MO7e cells. The ED50 for this effect is < 0.25 ng/mL. The specific activity of recombinant human IL-9 is approximately > 5 x 10^6 IU/mg.
Endotoxin level is less than 0.01 EU/μg of the protein, as determined by the LAL test.
Purity :
> 98% (by SDS-PAGE)
Applications :
SDS-PAGE
Notes :
For laboratory research only, not for drug, diagnostic or other use.
Storage :
Lyophilized protein should be stored at -20°C. After reconstitution, aliquot and store at -20°C or -80°C for up to one month. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening.
Storage Buffer :
PBS (pH 8.0)
Reconstitution :
It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min at room temperature to make sure the protein is dissolved completely.
