Human TfR

SKU: orb2992644

Description

Recombinant Human Transferrin receptor protein 1 is produced by our Mammalian expression system and the target gene encoding Cys89-Phe760 is expressed with a human IgG1 Fc tag at the N-terminus.

Key Properties

• Expression System: Human Cells
• Biological Origin: Human
• Biological Activity: ELISA: Immobilized Anti-Huamn TFRC mAb (Trontinemab) at 2 μg/ml (100 μl/well) can bind Recombinant Human TfR (C-Fc) (Cat#orb2992644)*. *:Biotinylated by NHS-biotin prior to testing. The ED50 of Recombinant Human TfR (C-Fc) (Cat#orb2992644) is 3.001 ng/ml. (Regularly tested).. BLI: Loaded Human TFRC Antibody (Trontinemab, Research Grade) (Cat#orb2992592) on Pro-A Biosensor, can bind Recombinant Human TfR (N-Fc) (Cat#orb2992644) with an affinity constant of 20.4 nM as determined in BLI assay.

Storage & Handling

• Storage: Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
• Form/Appearance: Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, 5% Trehalose, 5% Mannitol, 0.01% Tween80, pH 7.4.
• Reconstitution: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
