Product Specifications

Source: Human cells derived
Structure: Glycosylated monomer
Purity: >95% by SDS-PAGE
Endotoxin Level: <0.5EU/ug
Molecular Weight: ~15kDa
Formulation: Lyophilized from a 0.2μm filtered solution in PBS without carrier protein

Activity Assay

The specific activity was determined by the dose-dependent stimulation of the proliferation of mouse CTLL-2 cells (mouse cytotoxic T cell line).

Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile PBS containing 0.1% endotoxin-free recombinant human serum albumin.


Stability & Storage

Use a manual defrost freezer and avoid repeated freeze-thaw cycles. In general: 12 months from date of receipt, -20 to -80°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -80°C under sterile conditions after reconstitution.

Product Description:

Recombinant human IL-2 expressed in engineered human cells. IL-2 belongs to the IL-2 protein family. IL-2 is a 15 kDa glycosylated monomer. IL-2 is produced primarily by activated CD4+ T cells, but it is also expressed by naive CD8+ T cells, eosinophils, dendritic, and thymic cells. IL-2 is an essential activator of the immune response, it is required for the growth of T cells, activated B cells and T helper cell differentiation. IL-2 stimulates the activity of NK cells and is involved in anti-inflammatory reactions and in hematopoiesis.
