Introduction

IL2 is a secreted cytokine that is important for the proliferation of T and B lymphocytes. The receptor of this cytokine is a heterotrimeric protein complex whose gamma chain is also shared by interleukin 4 (IL4) and interleukin 7 (IL7). The expression of this gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests an essential role of this gene in the immune response to antigenic stimuli.

Description

Interleukin-2 Human Recombinant produced in HEK cells is a glycosylated monomer, having a total molecular weight of 15kDa.
The IL2 is purified by proprietary chromatographic techniques.

Source

HEK.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation

The IL2 was lyophilized from 0.2µm filtered solution containing 0.76mg/ml protein in 1xPBS.

Solubility

It is recommended to reconstitute the lyophilized IL-2 in sterile PBS containing 0.1% endotoxin-free recombinant HSA.

Stability

Lyophilized IL-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL2 should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Purity

Greater than 95% as obsereved by SDS-PAGE.

Biological Activity

The specific activity as determined by the dose-dependent stimulation of the proliferation of mouse CTLL-2 cells (mouse cytotoxic T cell line) was measured to be 1.57ng/ml.
