>IL-13 R alpha 1
Based on the high binding affinity between biotin-streptavidin systems, our Streptavidin series products are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.
This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 65.0 kDa. The protein migrates as 70-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
Biotinylated Human IL-13 R alpha 1, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
Biotinylated Human IL-13 R alpha 1, Fc,Avitag (Cat. No. IL1-H82F6) captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind Human IL-13, His Tag (Cat. No. IL3-H52H4) with an affinity constant of 45.6 nM as determined in a SPR assay (Biacore 8K) (QC tested).
