表达区间及表达系统（Source）
Biotinylated Human Transferrin R, His Tag, primary amine labeling is expressed from human HEK293 cells. It contains AA Cys 89 - Phe 760 (Accession # AAH01188.1). It is the biotinylated form of Human Transferrin R protein, His Tag (Cat. No. CD1-H5243).
Predicted N-terminus: His
Request for sequence蛋白结构（Molecular Characterization）
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.
偶联（Conjugate）
Biotin
标记（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.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
95% as determined by SDS-PAGE.
90% as determined by SEC-MALS.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
