HumanKine growth factors are expressed in a proprietary human 293 protein expression system and are manufactured without the use of any animal products and are considered Xeno-Free.

Interleukin-2 (IL-2) is commonly considered a pro-inflammatory cytokine that stimulated T-cell-dependent immune reactions and control regulatory T cells or Tregs. Structurally, IL-2 is thought to have a 4-helix-bundle-type fold and uses a novel type I cytokine receptor (IL-21R) with the common gamma chain cytokine receptor. IL-2 also may intensify Th1-mediated diseases, including autoimmune arthritis and may also be interesting clinical targets for those diseases. IL-2 has also been implicated as a possible therapy for infection and cancer. Anti-tumor therapies that include a combination of recombinant IL-2 and recombinant interferon alpha have been promising in clinical studies.

Product is presented in PBS and filtered through a 0.2 micron filter before lyophilization.

Store at -20°C for up to 4 months from date of receipt. Further dilutions should be made into appropriate buffer or medium to which protein has been added.

Bioactivity assay: Determined by the dose-dependent stimulation of the proliferation of mouse CTLL-2 cells (mouse cytotoxic T cell
line). ED50 is typically 0.2-2 ng/ml.

HumanKine IL-2 is manufactured using all non-animal reagents and is considered Xeno-Free
