Active Recombinant Human IL4 protein, His-tagged

• Cat.No.: IL4-0173H
• Product Overview: Recombinant Human IL4 protein(His25-Ser153), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human IL-4, His Tag at 5 μg/mL (100 μL/well) can bind Human IL-4 R alpha, Fc Tag with a linear range of 0.5-16 ng/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 16.9 kDa. The protein migrates as 22-24 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: His25-Ser153
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.>90% as determined by SEC-MALS.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
