| Purity | >98% as determined by SDS-PAGE. |
| Alternative | T-cell Growth Factor (TCGF), Aldesleukin |
| Formulation | The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 7.4. If you have any concerns or special requirements, please confirm with us. |
| Features & Benefits | Endotoxin: <0.1 EU per 1 μg of the protein by the LAL method. |
| Molecular weight | 18.2 kDa |
| Usage notes | Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Mouse IL-2 Protein, His tag (Animal-Free) using the buffer we provided not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. |
| Storage instructions | Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles. |
| Shipping | The product is shipped with blue ice. |

| Background | Interleukin-2 (IL-2) is a 18 kDa four bundle, immuno-modulatory cytokine which is expressed predominately by antigen-simulated CD4+ T cells, CD8+ T cells, natural killer (NK) cells, and dendritic cells (DC). IL-2 plays a fundamental role in promoting NK cell proliferation, cytotoxicity, and B cells differentiation. IL-2 modulate T cell differentiation programs, promoting naïve CD4+ T cell differentiation into T helper-1 (Th1) and T helper-2 (Th2) cells. |
| Alternative | T-cell Growth Factor (TCGF), Aldesleukin |
| Accession | P04351 |

1.The species of antibody reactivity should be the sample species that can be matched normally after Abbkine R&D experts have passed strict scientific verification. If your sample is not within the range of reactivity, in order to improve the efficiency and results of your experiment, it is not suggested to try other species. Otherwise, it may lead to sample mismatch and affect the effect of your experiment.
2.Please aliquot the antibody received as soon as possible and store it at -20℃, avoid repeated freezing and thawing, and use it within one year.
