uniprot entry name :
IL2_RAT
sequence :
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ala-Pro-Thr-Ser
purity :
Greater than 95.0% as determined by SDS-PAGE.
form :
The protein (1mg/ml) was lyophilized without any additives.
storage 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.
other info1 :
Physical Appearance: Sterile Filtered White Lyophilized (freeze-dried) powder.
other info2 :
Solubility: It is recommended to reconstitute the lyophilized Interleukin 2 in sterile 100mM AcOH not less than 100 ug/ml, which can then be further diluted to other aqueous solutions. Protein Content: Protein quantitation was carried out by two independent methods:. 1. UV spectroscopy at 280 nm using the absorbency value of 0.535 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of IL-2 as a Reference Standard. Biological Activity: The ED50 as determined by the dose-dependant stimulation of murine CTLL-2 cells is 0.1-0.4 ng/ml corresponding to a specific activity of 2,500,000-10,000,000 units/mg.

products description :
Description: Interleukin-2 Rat Recombinant produced in E Coli is a single, non-glycosylated polypeptide chain containing 134 amino acids and having a molecular mass of 17kDa. The IL-2 is purified by proprietary chromatographic techniques. 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.

ncbi summary :
cytokine produced by T-cells in response to antigen or mitogen stimulation [RGD, Feb 2006]
uniprot summary :
Produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Can stimulate B-cells, monocytes, lymphokine-activated killer cells, natural killer cells, and glioma cells.
