| Product name | Human IL-4 Protein |
| Sequence | Amino acid sequence derived from Human IL-4 (His25-Ser153) (P05112-1) was expressed. |
| Activity | Measured by its ability to induce proliferation in TF-1 cells. The ED50 for this effect is 0.5308 ng/mL. |
| Protein length | The recombinant Human IL-4 consists of 129 amino acids and predicts a molecular mass of 15.1 kDa. |
| Preparation method | E. coli |
| Purity | > 98 % as determined by SDS-PAGE |
| Alternative | IL-4; Interleukin 4; BCGF1; BSF1 |
| 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: <1 EU per 1 μg of the protein by the LAL method. |
| Molecular weight | 15.1 kDa |
| Usage notes | Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized protein using the buffer we provided not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. |

| Background | Human Interleukin-4 (IL-4) is a cytokine that plays an important role in regulating inflammation and immune responses. It induces the differentiation of T cells to Th2 cells. This cytokine binds the IL-4 receptor that also binds another cytokine interleukin 13 (IL-13), which may explain the overlapping functions of IL-4 and IL-13. |
| Gene ID | 3565 |
| Alternative | IL-4; Interleukin 4; BCGF1; BSF1 |

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.
