| 产品介绍 | background: The protein encoded by this gene is a pleiotropic cytokine produced by activated T cells. This cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. This gene, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]. Function: Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. Subcellular Location: Secreted. DISEASE: Genetic variations in IL4 may be a cause of susceptibility to ischemic stroke (ISCHSTR) [MIM:601367]; also known as cerebrovascular accident or cerebral infarction. A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. Similarity: Belongs to the IL-4/IL-13 family. SWISS: P05112 Gene ID: 3565 Database links:

文献和实验学功能活性，还有利于维持细胞因子的稳定性，延长其半衰期。 图4 不同宿主表达IL-4在细胞培养基中的稳定性比较(37C, 5 days) 例如白介素4，如上图所示：人源细胞表达生产的IL-4由于具有正确完整糖基化修饰，SDS-PAGE的表观分子量为20 kDa左右，而E.Coli来源的IL-4缺乏糖基化，因而分子量仅为14 kDa。由于具有正确的糖基化，因此，将等量两种不同宿主来源的细胞因子加入到细胞培养基中在37度下培养5天后，细菌来源的白介素4活性显著降低
69、CD38 等活化指标，及 IFN-γ、IL-4、IL17A 等细胞因子，则需要设置同型对照，实现阴阳性细胞群的良好区分。 CD4 CD25 （2）在某些特殊情况下，如单核细胞被 PE/Cyanine 7、APC/Cyanine 7 等串联染料标记的抗体染色时，使用同型对照抗体是十分有必要的。单核细胞一般倾向于与 Cyanine7 等染料非特异性结合，使用同型对照抗体有助于获得理想结果。 （3）不清楚抗原表达情况的时候，一定要使用同型对照来界定阴性细胞群。 （4）胞内染色时
