| Cat. No. : | TF-4777H |
| Product Overview : | Product is the lyophilized powder of human TF and buffer salts. Human TF is purified from pooled human serum using multi-step procedures which may include salt fractionation, gel filtration, ion-exchange chromatography and immunoabsorption. The product is dialyzed into 0.01M sodium phosphate, 0.07M sodium chloride, pH 7.3, filtered through a 0.22 µm filter, vialed and lyophilized. No preservative has been added. |
| Description : | TF is a glycoprotein that binds iron very tightly but reversibly. Although iron bound to transferrin is less than 0.1% (4 mg) of the total body iron, it is the most important iron pool, with the highest rate of turnover (25 mg/24 h). TF has a molecular weight of around 80 kDa and contains 2 specific high-affinity Fe (III) binding sites. |
| Source : | Human Plasma |
| Species : | Human |
| Preparation : | The protein is purified from pooled human plasma and lyophilized from 0.02M NH4HCO3. |
| Reconstitution : | The protein is readily soluble at 1% in deionised. Alternatively, it can be reconstituted with a neutral buffer, such as PBS. |
| SDS-PAGE : | The preparation shows a tight cluster of bands with a molecular weight of 77 kDa. Dimers may appear under certan conditions. |
| Protein : | 98% (By Lowry) |
| Purity : | > 98 % (By Cellulose Acetate Electrophoresis) |
| Iron : | 27.85 µg/g (By Atomic Absorption). 1 gm transferrin can bind approximately 1400-1500 µg of iron. |
| pH : | 7.24 (3% solution) |
| Endotoxin Level : | 0.034 EU/mg (By Limulus Amebocyte Lysate) |
| Microbial detection : | No Mycoplasma is detected and Bioburden is less than 10 cfu/ml. |
| Moisture : | 0.9 % (By Loss on Drying) |
| Storage : | Store at -10°C or below. |
| Pathways : | EPHB forward signaling; Formation of Platelet plug; HIF-1-alpha transcription factor network; Hemostasis; Iron uptake and transport; Mineral absorption; Platelet Activation; Platelet degranulation; Response to elevated platelet cytosolic Ca2+; Transferrin endocytosis and recycling; Transmembrane transport of small molecules |
