IL-7 (Interleukin 7)

Product Description:

  • Endotoxin-free
  • Animal-derived product free
  • Lyophilized and Carrier Free (CF)
  • Higher Activity

Xeno-free IL-7HuXp is expressed in Human 293 cells as a highly glycosylated protein. Under reducing conditions, IL-7 migrates as three separate bands as 19 kDa, 25 kDa and 30 kDa. In comparison IL-7 produced in an E. coli expression system have glycosylation and migrate as a single band at 17 kDa. IL-7 is a hematopoietic cytokine that is important for B and T cell development. When combined with other factors, IL-7 can also co-stimulate the proliferation of mature T cells. Production in human 293 cells uses a serum-free, chemically defined media and offers authentic glycosylation.

Technical Specifications:

  • Species: Human
  • Expression: HEK293 Cell Expressed
  • Activity: Typically ≤ 1 ng/mL EC50
  • Purity: >95%
  • Endotoxin: <1 EU/μg
  • Molecular Mass: 19, 25, and 30 kDa, monomer, glycosylated
  • Formulation: 1x PBS

Purity Confirmation:

The protein was resolved by SDS-polyacrylamide gel electrophoresis and the gel was stained with Coomassie blue.

Activity Assay:

The specific activity was determined by the dose- dependent stimulation of the proliferation of murine 2E8 cells.

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).

Synonyms: Lymphopoietin 1(LP-1), pre-B cell factor Lymphopoietin 1(LP1), Lymphopoietin 1(LP 1)
