Interleukin-15 Mouse Recombinant ( IL 15 Mouse )

Data sheet

Formulation

The protein was lyophilized from a concentrated (1mg/ml) solution with 10mM NaP pH 8.0.

Solubility

It is recommended to reconstitute the lyophilized Interleukin-15 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Inactivation

Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.924 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program o

Description

Interleukin-15 Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 115 amino acids and having a molecular mass of 13321 Dalton. The IL-15 is purified by proprietary chromatographic techniques.

Protein Background

The protein encoded by this gene is a cytokine that regulates T and natural killer cell activation and proliferation. This cytokine and interleukine 2 share many biological activities. They are found to bind common hematopoietin receptor subunits, and may

Expression host

Escherichia Coli.

Synonyms

IL-15, MGC9721.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Interleukin-15 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL15 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended t

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Met-Asn-Trp-Ile-Asp.

Biological Activity

The ED50 as determined by the dose-dependant stimulation of the proliferation of mouse CTLL-2 was found to be 15 ng/ml, corresponding to a Specific Activity of 2 x 105 IU/mg.
