Product Description:
- Endotoxin-free
- Animal-derived product free
- Lyophilized and Carrier Free (CF)
- High Activity
Xeno-free IL-9HuXp is expressed from human 293 cells as a glycoprotein monomer with apparent molecular mass of 38 to 48 kDa. IL-9 is produced in a human cell expression system with serum-free, chemically defined media. It stimulates cell proliferation and also prevents apoptosis. IL-9 acts as a regulator for a variety of hematopoietic cells. It enhances the expansion and recruitment of mast cells and eosinophils. This cytokine is greater than 95% pure.
Technical Specifications:
- Species: Human
- Expression: HEK293 Cell Expressed
- Activity: Typically ≤ 1 ng/mL EC50
- Purity: >95%
- Endotoxin: <1 EU/μg
- Molecular Mass: 38 to 48 kDa, monomer, glycosylated

Purity Confirmation:
The protein was resolved by SDS-polyacrylamide gel electrophoresis and the gel was stained with Coomassie blue.
Activity Assay:
The activity was determined by the dose-dependent stimulation of the proliferation of human MO7e cells (human megakaryoblastic leukemia cell line).
Reconstitution Buffer:
Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 1xPBS containing 0.1% endotoxin-free recombinant human serum albumin (HSA).
