Interleukin-13 Variant Human Recombinant（IL 13 Variant Human）
产品编号：CYT-682
产品规格：2μg/10μg/1mg
Synonyms
Interleukin-13, NC30, ALRH, BHR1, P600, IL-13, MGC116786, MGC116788, MGC116789.
Introduction
IL13 is an immunoregulatory cytokine produced primarily by activated Th2 cells. IL-13 is involved in several stages of B-cell maturation ａnd differentiation. It up-regulates CD23 ａnd MHC class II expression, ａnd promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines ａnd chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE ａnd eosinophils. This gene, IL3, IL5, IL4, ａnd CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL4.
Description
Interleukin-13 Variant Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 114 amino acids, with a substitution of Q for R at position 112 compared with the wild type IL-13, having a molecular mass of 12.5 kDa.
The IL-13 Variant is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized （freeze-dried） powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 1xPBS, pH 7.2, containing 5% trehalose.
Solubility
It is recommended to reconstitute the lyophilized Interleukin 13 Variant in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized Interleukin-13 Variant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL13 Variant should be stored at 4°C between 2-7 days ａnd for future use below -18°C.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles.
Purity
Greater than 95% as determined by（a） Analysis by RP-HPLC.
（b） Analysis by SDS-PAGE.
Amino acid sequence
SPGPVPPSTA LRELIEELVN ITQNQKAPLC NGSMVWSINL TAGMYCAALE SLINVSGCSA IEKTQRMLSG FCPHKVSAGQ FSSLHVRDTK IEVAQFVKDL LLHLKKLFRE GQFN.
Biological Activity
The ED50 was determined by the dose dependent prolifiration of TF-1 cells ａnd was found to be < 1ng/ml, corresponding to a specific activity of >1,000,000 units/mg. This analog has also been shown to exhibit increased in vivo activity compared to wild type IL-13.
