ActoFactor™ Recombinant Rat Interleukin 13 (109 aa Variant)
- Specification
Cat.No.
CSC-CTK0826
Description
IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and also by mast cells and NK cells. Targeted deletion of IL-13 in mice resulted in impaired Th2 cell development and indicated an important role for IL-13 in the expulsion of gastrointestinal parasites. IL-13 exerts anti-inflammatory effects on monocytes and macrophages and it inhibits the expression of inflammatory cytokines such as IL-1beta, TNF-alpha, IL-6 and IL-8. IL-13 has also been shown to enhance B cell proliferation and to induce isotype switching resulting in increased production of IgE. Blocking of IL-13 activity inhibits the pathophysiology of asthma. Human and murine IL-13 is cross-species reactive. Recombinant rat IL-13 is an 11.9 kDa protein consisting of 109 amino acid residues.
Species
Rat
Product Overview
Rat Il13 expressed in E.coli
Molecular Mass
11.9 kDa
Size
CAT# CSC-CTK0826-10 (10 μg); CAT# CSC-CTK0826-50 (50 μg)
Expression System
E.coli
Purity
Greater than 98% as determined by SDS-PAGE and HPLC analysis.
Activity
The ED50 as determined by the dose-dependant stimulation of the proliferation of human TF-1 cells is 2.5 x 104 units/mg.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Lyophilized from a sterile-filtered solution with no additives.
Reconstitution
Please centrifuge product before opening vial. The lyophilized protein should be reconstituted with distilled, sterile water to a concentration of 0.1-1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
