TFR1(CD71) is a single-pass type II membrane protein in the peptidase M28 family. It is highly expressed in proliferating cells and solid tumors, serving as a diagnostic and therapeutic target. Essential for erythrocyte and nervous system development, TFRC is post-transcriptionally regulated by cellular iron levels via IRP1/IRP2 binding to 3'-UTR iron-responsive elements. Its expression is upregulated upon mitogenic stimulation and is a marker of pancreatic malignant transformation.
| Synonyms | CD71, TFRC, TFR, sTfR, TfR1, Trfr, T9, p90 |
|---|---|
| Protein Construction ＆ Source | ·Recombinant Human(Uniprot: P02786-1) TFR1 Protein is expressed from HEK293 cells with hFc(IgG1) tag at the N-terminus.It contains AA Lys 189- Glu 383.·The protein has a predicted MW of 50.7 kDa. The protein migrates as 55-70 kDa when calibrated against under reducing (R) condition (SDS-PAGE) due to glycosylation. |
| Endotoxin | < 0.1 EU per ug as determined by the LAL method. |
| Purity | > 95% as determined by SDS-PAGE. |
| Concentration ＆ Formulation | ·3.1 mg/mL ·Filtered through a 0.22 μm filter, stored in 25 mM Sodium Citrate, 1x PBS,pH 7.4. |
| Transportation ＆ Storage | ·This product is shipped under low-temperature conditions. Avoid repeated freeze-thaw cycles during handling.·Protein solution can be stored at 2-8°C for 2-7 days.·Samples are stable for 3 months from date of receipt at -20℃ /-80℃. ·Recommend to aliquot the protein into smaller quantities for optimal storage. |
