Recombinant Human Interleukin-9/IL-9/Cytokine P40 (C-6His)

Source: Human Cells. MW :15.16kD. Recombinant Human Interleukin-9 is produced by our Mammalian expression system and the target gene encoding Glu19-Ile144 is expressed with a 6His tag at the C-terminus. Interleukin-9 (IL-9) is a secreted protein that belongs to the IL-7/IL-9 family. IL-9 supports IL-2 independent and IL-4 independent growth of helper T-cells. IL-9 stimulates cell proliferation and prevents apoptosis. It functions through the IL-9 receptor (IL-9R), which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. IL-9 has been identified as a candidate gene for asthma. IL-9 is a determining factor in the pathogenesis of bronchial hyperresponsiveness.

Components

Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl, pH7.4.

Shipping Conditions

The product is shipped at ambient temperature.

Storage Conditions

Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.

Applications Notes

Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. Endotoxin : Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.
