With carrier: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.2 containing 20 μg BSA per 1 μg mIL-13. Carrier free: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.2.
Stable in lyophilized state at -20°C for 1 year after receipt. Sterile stock solutions reconstituted with carrier protein are stable at 4°C for 2 months and at -20°C for 6 months. Avoid repeated freeze-thaw cycles.
Maintain sterility. Storage at -20°C should be in a manual defrost freezer.
|Purity||>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mIL-13. All lots are greater than 98% pure.|
|Endotoxin||Less than 0.01 ng endotoxin/1μg mIL-13.|
|Activity||The bioactivity of recombinant mIL-13 was determined in a B9 cell proliferation assay. The ED50 of each lot is between 0.5 - 20 ng/ml.|
|Molecular Formula||Recombinant mIL-13 contains no "tags" and the nonglycosylated protein has a calculated MW of 11,677. DTT-reduced and non-reduced protein migrate as 12-20 kDa polypeptides. Lower mobility and heterogeneity in SDS-PAGE are due to glycosylation. The expected amino-terminal SVSLP of recombinant mIL-13 was verified by amino acid sequencing.|
Recombinant mouse IL-13 (mIL-13) Ser26-Phe131 (Accession #NP_032381) was expressed in human 293 cells at Cell Signaling Technology.
