IL 2 Human, Yeast
Interleukin-2 Human Recombinant, Yeast
Catalog No. CYT-604
Synonyms:
Interleukin-2, T-cell growth factor (TCGF), Aldesleukin, Lymphokine, IL-2.
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 yeast is a single, glycosylated polypeptide chain containing 133 amino acids and having a molecular mass of 15 kDa.
The IL-2 is purified by proprietary chromatographic techniques.
Source:
Saccharomyces cerevisiae
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:
The protein (1.1mg/ml) was lyophilized after extensive dialysis against 20mM phosphate buffer to a pH=7.6.
Solubility:
It is recommended to reconstitute the lyophilized Interleukin-2 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability:
Lyophilized Interleukin-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 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Biological Activity:
The biological activity is tested in a cell proliferation assay using an IL-2 dependent murine cytotoxic T cell line.
Usage:
ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
