The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
The ED50 as determined by the dose-dependent stimulation of murine CTLL-2 cells is ≤ 0.1 ng/ml, corresponding to a specific activity of ≥ 1 x 107 units/mg.
内毒素水平< 0.100 Eu/µg
补充说明The ED50, determined by the dose-dependent stimulation of murine CTLL-2 cells, is < 0.1 ng/ml, corresponding to a specific activity of > 1 x 107 units/mg.

This product is an active protein and may elicit a biological response in vivo, handle with caution.
复溶Centrifuge the vial prior to opening. Reconstitute in 100 mM Acetic Acid to a concentration of 0.1-1.0 mg/ml. This solution can then be
diluted into other aqueous buffers and stored at 4oC for 1 week or -20oC for future use.
Involved in regulation of T cell clonal expansion
T Cell Growth Factor
T-cell growth factor
功能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.
疾病相关Note=A chromosomal aberration involving IL2 is found in a form of T-cell acute lymphoblastic leukemia (T-ALL). Translocation t(4;16)(q26;p13) with involves TNFRSF17.
