Human IL-4 Protein (IL4-HM201) Summary

Product Description	Recombinant Human IL-4 Protein is expressed from HEK293 with hFc (IgG1) tag at the C-terminus.It contains His25-Ser153.
Product Background	Interleukin-4, also known as IL4, is a secreted protein which belongs to the IL-4/IL-13 family. Interleukin-4/IL4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation. In the presence of IL-4 and IL-13, cytokines that are produced in a Th-2 type response, particularly during allergy and parasitic infections, macrophages become differentially activated, and this cytokine is a ligand for interleukin 4 receptor.

Molecular Weight	The protein has a predicted MW of 40.9 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human IL-4 R alpha, His Tag (Cat. ILA-HM14R) at 1ug/ml (100ul/well) on the plate. Dose response curve for Human IL-4, hFc Tag with the EC50 of 3.3ng/ml determined by ELISA.
Product Tag	C-hFc (IgG1)
Fluorophore	Unconjugated
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 0.1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). 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-4 R alpha, His Tag (Cat. ILA-HM14R) at 1ug/ml (100ul/well) on the plate. Dose response curve for Human IL-4, hFc Tag with the EC50 of 3.3ng/ml determined by ELISA.
	Human IL-4 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
	The purity of Human IL-4 is greater than 95% as determined by SEC-HPLC.
