16183 |
Accession | P04351 |
Alternative Name | IL-2, T-cell growth factor, TCGF<br/>Recombinant Mouse Interleukin-2 (IL2) |
Species | Mouse |
Source | E. coli |
Description | IL-2 is produced mainly by T cells expressing the surface antigen CD4 following cell activation by mitogens or allogen. Interleukin-2 (IL-2) has multiple, sometimes opposing, functions during an inflammatory response. It is a potent inducer of T cell proliferation and Th1 and Th2 effector T cell differentiation and provides T cells with a long-lasting competitive advantage resulting in the optimal survival and function of memory cells. In a regulatory role, IL-2 is important for the development, survival, and function of regulatory T cells, it enhances Fas-mediated activation-induced cell death, and it inhibits the development of inflammatory Th17 cells. Thus, in its dual and contrasting functions, IL-2 contributes to both the induction and the termination of inflammatory immune responses. |
Accession | P04351 |
Functions | 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. |
Formulation | Recombinant mouse IL-2 was lyophilized from 0.2 ?m filtered PBS solution, pH 7.0. |
Solubility | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
Appearance | Lyophilized Powder |
Molecular Weight | 17 |
Purity | >95% as determined by SDS-PAGE |
Concentration | < 1.0 EU/μg of recombinant protein as determined by the LAL method. |
Shipping Condition | Ambient Temperature |
Storage Condition | The lyophilized protein is stable for at least one year from date of receipt at -70?C. Upon reconstitution, this cytokine can be stored in working aliquots at 2? - 8?C for one month, or at -20?C for six months, with a carrier protein without detectable loss of activity.
Avoid repeated freeze/thaw cycles. |
