Human IL-9 Protein (IL9-HM101) Summary

Product Description	Recombinant Human IL-9 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln19-Ile144.
Product Background	IL-9 is a pleiotropic cytokine that influences various distinct functions of different target cells such as T cells, B cells, mast cells and airway epithelial cells by activating STAT1, STAT3 and STAT5. Because of its pleiotropic functions, IL-9 has been demonstrated to be involved in several diseases, such as cancer, autoimmunity and other pathogen-mediated immune-regulated diseases.

Human IL-9 Protein (IL9-HM101) Specifications/Details

Protein	IL-9
Synonyms	Interleukin-9; IL-9; Cytokine P40; T-cell growth factor P40; HP40; P40
Accession	P15248
Species	Human
Biotinylated	no
Amino Acid Range	Gln19-Ile144
Molecular Weight	The protein has a predicted MW of 15.3 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human IL-9, His Tag at 0.5ug/ml (100ul/Well) on the plate. Dose response curve for Anti-IL-9 Anitibody, hFc Tag with the EC50 of 5.5ng/ml determined by ELISA (QC Test).
Product Tag	C-His
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in 20mM Tris, 150mM NaCl (pH 7.5). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

	Immobilized Human IL-9, His Tag at 0.5ug/ml (100ul/Well) on the plate. Dose response curve for Anti-IL-9 Anitibody, hFc Tag with the EC50 of 5.5ng/ml determined by ELISA (QC Test).
	Human IL-9 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
	Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50-for this effect is < 0.3 ng/mL (QC Test).
	The purity of Human IL-9 is greater than 95% as determined by SEC-HPLC.
