产品概述

Description
Interleukin-2(IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system,belongs to the IL-2 family. It is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation.  IL-2/IL-2R signaling is required for T-cell proliferation and other fundamental functions that are essential for the immune response.  IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine-activated killer cells, monocytes, macrophages and oligodendrocytes.

Origin
Recombinant Human Interleukin-2 is produced by our E.coli expression system and the target gene encoding Ala21-Thr153 is expressed. 
 
Quality control
Greater than 95% as determined by reducing SDS-PAGE.

Endotoxin
Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test.

Biological Activity
Bioactivity:    Measured in a cell proliferation assay using CTLL-2 mouse cytotoxic T cells.The specific activity of Recombinant Human IL-2 is ≥1×107 IU/mg.

Formulation
Lyophilized from a 0.2 μm filtered solution of 10mM sodium citrate, pH 4.0.

Reconstitution
Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a
concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Storage condition
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.

For Research Use Only. Not for use in diagnostic procedures.
