| 产品名称 | Recombinant Human IL-2 | 蛋白编号 | P60568 |
| 产品别称 | Interleukin-2; IL-2; T-Cell Growth Factor; TCGF; Aldesleukin; IL2 | ||
| 产品描述 | Recombinant Human Interleukin-2 is produced by our E.coli expression system and the target gene encoding Ala21-Thr153 is expressed. | ||
| 分子量 | Mol Mass:15.5 KDa; APMol Mass:14 KDa, reducing conditions | 剂型描述 | Lyophilized from a 0.2 μm filtered solution of 10mM sodium citrate, pH 4.0. |
| 内毒素 | < 0.01 EU/µg as determined by LAL test. | 纯度 | Greater than 95% as determined by reducing SDS-PAGE. (QC verified) |
| 生物活性 | 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. (QC verified) | ||
| 复溶 | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | ||
| 保存条件 | Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months. | ||
| 运输条件 | The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below. | ||
| 产品背景 | 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. | ||
