Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the N-terminus and an Avi tag (Avitag™) at the C-terminus.
The protein has a calculated MW of 19.9 kDa. The protein migrates as 27-35 kDa 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.
