Other Tags and Version Biotin & Other Labeled Version
This protein carries an Avi tag (Avitag™) at the N-terminus, followed by a human IgG1 Fc tag.
The protein has a calculated MW of 35.3 kDa. The protein migrates as 38-42kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Labeling
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Protein Ratio
Passed as determined by the HABA assay / binding ELISA.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Performance Data
SDS-PAGE
Biotinylated Human IGF-II, Avitag,Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
Bioactivity-ELISA
Immobilized Human IGFBP-3, His Tag (Cat. No. IG3-H52H9) at 5 μg/mL (100 μL/well) can bind Biotinylated Human IGF-II, Avitag,Fc Tag (Cat. No. IG2-H82F9) with a linear range of 1.2-39 ng/mL (QC tested).
Protocol
Bioactivity-SPR
Biotinylated Human IGF-II, Avitag,Fc Tag (Cat. No. IG2-H82F9) captured on Protein A Chip can bind Human IGF-II R Protein, His Tag (Cat. No. IGR-H53H3) with an affinity constant of 189 nM as determined in a SPR assay (Biacore 8K) (Routinely tested).
