Name : Human Transferrin R/CD71 Protein
Product Source :
Recombinant Human Transferrin R/CD71 Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus. It contains Cys89-Phe760.[Accession | P02786]
Molecular Weight :
The protein has a predicted MW of 77.9 kDa. Due to glycosylation, the protein migrates to 78-80 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human Transferrin R on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human Transferrin R is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human Transferrin R, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-Transferrin R Antiboy, hFc Tag with the EC50 of 6.3ng/ml determined by ELISA (QC Test). SPR Data Human Transferrin, His Tag immobilized on CM5 Chip can bind Human Transferrin R, His Tag with an affinity constant of 27.50 nM as determined in SPR assay (Biacore T200).
Background :
The transferrin receptor (CD71) is known as a receptor for IgA1 on mesangial cells. The transcript and protein expression of glomerular CD71 was determined by real-time polymerase chain reaction and immunohistochemistry. Human mesangial cells (HMCs) were treated with sera from IgAN patients and expression levels of CD71 and inflammatory cytokine markers were compared according to disease status.
Synonyms :
TR; TfR1; CD71; sTfR; T9; p90; TFRC; TFR
