Source

Biotinylated Human Transferrin R, His Tag, primary amine labeling (TFR-H8243) is expressed from human 293 cells (HEK293). It contains AA Cys 89 - Phe 760 (Accession # AAH01188.1). It is the biotinylated form of Human Transferrin R, His Tag.

Predicted N-terminus: His

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 76.0 kDa. The protein migrates as 75-85 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a dimer.

Labeling

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

Protein Ratio

Passed as determined by the HABA assay / binding ELISA.

Purity

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
