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. IL4 is considered an important cytokine for tissue repair, counterbalancing the effects of proinflammatory type 1 cytokines, however, it also promotes allergic airway inflammation. Moreover, IL-4, a type 2 cytokine, mediates and regulates a variety of human host responses such as allergic, anti-parasitic, wound healing, and acute inflammation. This cytokine has been reported to promote resolution of neutrophil-mediated acute lung injury. In an allergic response, IL-4 has an essential role in the production of allergen-specific immunoglobin (Ig) E. This pro-inflammatory cytokine has been observed to be increased in COVID-19 (Coronavirus disease 2019) patients, but is not necessarily associated with severe COVID-19 pathology. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Polyclonal Antibodies\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IF-P, IHC-P, ELISA\u003c\/p\u003e\n\n\u003cp\u003eCross-reactivity: Human\u003c\/p\u003e\n\n\u003cp\u003eProtein Weight: 17kDa\u003c\/p\u003e\n\n\u003cp\u003eObserved Molecular Weight: 20kDa\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Recombinant protein (or fragment) .\u003c\/p\u003e\n\n\u003cp\u003eSpecies: Human\u003c\/p\u003e\n\n\u003cp\u003eGeneID: 3565\u003c\/p\u003e\n\n\u003cp\u003eSWISS: P05112\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: BSF1; IL-4; BCGF1; BSF-1; BCGF-1; IL4\u003c\/p\u003e\n\n\u003cp\u003eSource: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eIsotype: IgG\u003c\/p\u003e\n\n\u003cp\u003ePurity: Affinity purification\u003c\/p\u003e\n\n\u003cp\u003eStorage: Store at -20℃.
