Product Description

Interleukin-2 (IL-2) is a cytokine, which is a type of signaling molecule that plays a crucial role in the immune system. It is produced by certain immune cells, particularly T cells, in response to antigen stimulation. IL-2 was originally identified for its ability to stimulate the growth and proliferation of T cells, making it a key regulator of immune responses. 

Our products are produced using a proprietary plant based expressed system.

  • Animal Component Free (ACF). No endotoxins, prions or virons to risk microbial contamination.
  • Highly flexible platform used to produce multiple proteins with minimal changes to method.
  • Our proteins generally have 10% to 20% higher activity.
  • Our fusion tech is highly-engineered and tested to be hyper-thermal stable and protease-resistant.

MNPharm Guarantee

If your product IL2 is within its expiration period, and has not performed according to expectations, fill out the sample return form. Return the unused sample frozen, with the auto generated packing slip to the address on the instructions. You will receive a full refund along with a replacement of the unused portion (inclusive of the failed test). Damages do not cover any additional costs incurred for failed experimentation. 


Storage Instructions

Reconstituted store at -20°C or -80°C.
We recommend that single use aliquots are prepared to avoid freeze-thaw cycles."

Reconstitution Instructions 

  1. Thaw the vial on ice, spin briefly
  2. Prepare single-use or stock aliquots. This stage will depend on your final application so please adapt as appropriate. All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 ug/ml) adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
  3. Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles which can damage the proteins and reduce bioactivity. Store aliquots at -70 °C (or -20 °C)
  4. We recommend sterile filtering after dilution in media or the final working solution
