Human Interleukin-4 protein (Recombinant) {Biotin} (STJP000191)
SPECIFICATIONS
HostHEK293
ConjugationBiotin
ImmunogenDNA sequence encoding Human IL4 including a C-terminal AVI polyHis tag was expressed in HEK293 cells. Recombinant Human IL4 was further labeled by Biotin for detection by avidin conjugated secondary probes. NA
General Information

Product Properties
| Conjugation | Biotin |
| Dilution Range | Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers. |
| Formulation | Lyophilised from 0.2 µm filtered PBS solution pH7.4. |
| Storage Instruction | The lyophilized protein is stable for at least 1 year from date of receipt at-20°C. NA |
| Endotoxin | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). NA |
| Immunoreactivity | The activity was tested by the ability to bind human IL4R in an ELISA assay at a linear range of 2-10 ng/ml. NA |

Additional Info
| Function | Cytokine secreted primarily by mast cells, T-cells, eosinophils, and basophils that plays a role in regulating antibody production, hematopoiesis and inflammation, and the development of effector T-cell responses. Induces the expression of class II MHC molecules on resting B-cells. Enhances both secretion and cell surface expression of IgE and IgG1. Also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. Positively regulates IL31RA expression in macrophages. Stimulates autophagy in dendritic cells by interfering with mTORC1 signaling and through the induction of RUFY4. In addition, plays a critical role in higher functions of the normal brain, such as memory and learning. Upon binding to IL4, IL4R receptor dimerizes either with the common IL2R gamma chain/IL2RG to produce the type 1 signaling complex, located mainly on hematopoietic cells, or with the IL13RA1 to produce the type 2 complex, which is also expressed on nonhematopoietic cells. Engagement of both types of receptors initiates JAK3 and to a lower extend JAK1 phosphorylation leading to activation of the signal transducer and activator of transcription 6/STAT6. |
