Source

Biotinylated Rat Transferrin R Protein, Avitag,His Tag (TFR-R82E3) is expressed from human 293 cells (HEK293). It contains AA Gly 87 - Phe 761 (Accession # Q99376-1).

Predicted N-terminus: Gly

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries an Avi tag (Avitag™) at the N-terminus, followed by a polyhistidine tag.

The protein has a calculated MW of 79.8 kDa. The protein migrates as 70-85 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a dimer.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
