Source

Biotinylated Mouse Transferrin Protein, His,Avitag (TRN-M82E3) is expressed from human 293 cells (HEK293). It contains AA Val 20 - His 697 (Accession # Q921I1-1).

Predicted N-terminus: Val 20

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

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

The protein has a calculated MW of 78.7 kDa. The protein migrates as 75-95 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.

Protein Ratio

Passed as determined by the SABA assay / HABA assay / binding ELISA.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, 0.2 M Arginine, pH7.4.

Background

Transferrin (TF), also known as Serotransferrin or Beta-1 metal-binding globulin, is an iron-binding glycoprotein in blood plasma responsible for controlling free iron levels in biological fluids. It represents the most dynamic iron pool in the body, exhibiting high affinity for Fe(III) at physiological pH. This 679-amino acid polypeptide, primarily synthesized in the liver, comprises two globular lobes (N- and C-terminal) forming iron-binding sites. Transferrin plays a key role in iron withholding within the innate immune system, exerting a bacteriocidal effect. Its levels decrease during inflammation, and it significantly influences plutonium biochemistry in humans. Carbohydrate-deficient transferrin serves as a biomarker for heavy ethanol consumption.
