Recombinant Mouse Interleukin-25 (IL25)
|Description||IL-25 (also known as IL- 17E), a member of the IL-17 family, has been implicated in Th2 cell-mediated immunity. Recently, IL-25 has been identified as one of the initiators of the Th2 response (10, 11) and has also been shown to be expressed by mast cells. The transgenic overexpression of IL-25 by lung epithelial cells results in mucus hyperproduction and airway infiltration of macrophages and eosinophils; conversely, IL-25 blockade reduced airway inflammation and Th2 cytokine production in an allergen-induced asthma model.|
|Molecular Weight||16.0 kDa|
|Endotoxin Level||<1.0 EU/μg of recombinant protein as determined by the LAL method|
|Purity||>95% as determined by SDS-PAGE|
|Bioactivity||The ED(50) was determined by the dose-dependent proliferation of human umbilical vein endothelial cells and was found to be <0.5ng/mL.|
|Formulation||Lyophilized from 0.2μm filtered solution in Tris and NaCl|
|Reconstitution||A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.|
|Storage||Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.|
|Usage||For research use only. Not for diagnostic or therapeutic use.|
· Endotoxin is generally measured in Endotoxin Units per milliliter (EU/mL).
· For recombinant proteins: EU is reported per microgram of protein.
· One EU = 0.1-0.2 ng endotoxin/µg of protein.
· At abm, we do the LAL chromogenic assays that can detect down to 0.01 EU/ml.
