Active Recombinant Human IL7 protein

• Cat.No.: IL7-506H
• Product Overview: Recombinant Human IL7 protein (Asp26-His177) carries no tag and was expressed in human 293 cells (HEK293).

Specification

• Source: HEK293
• Species: Human
• Tag: N/A
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Human IL-7, premium grade stimulates proliferation of PHA-P-activated human peripheral blood mononuclear cell (PBMC). The EC50 for this effect is 1.565 ng/mL, corresponding to a specific activity of > 1.0 ⅹ10^8 IU/mg, which is calibrated against human IL-7 WHO International Standard (NIBSC code: 90/530).
• Molecular Mass: The protein has a calculated MW of 17.4 kDa. The protein migrates as 24 kDa and 25-28 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Protein Length: Asp 26 - His 177
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 centigrade to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade 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℃ before opening to recover the entire contents.
