Purification notesab84242 was purified by affinity chromatography and then biotinylated and filter sterilised.
Our Abpromise guarantee covers the use of ab84242 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
sELISA: Use at a concentration of 0.25 - 1 µg/ml. Allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human IL4.
WB: Use at a concentration of 0.1 - 0.2 µg/ml. The detection limit for recombinant Human IL4 is 1.5 - 3.0 ng/lane under either reducing or non-reducing conditions. Predicted molecular weight: 17 kDa.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionParticipates 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.
Involvement in diseaseGenetic 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.
Sequence similaritiesBelongs to the IL-4/IL-13 family.
