| Purity | ≥95 % as determined by SDS-PAGE |
| Alternative | PRO2086 Protein; TFQTL1 Protein; HEL-S-71p Protein, Human; PRO1557 Protein; Transferrin Protein,Siderophilin, partially saturated |
| Formulation | Lyophilized from sterile PBS, pH 7.4. |
| Molecular weight | 76.6 kDa |
| Usage notes | Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human Transferrin protein using the buffer we provided not less than 100 µg/mL, which can then be further diluted to other aqueous solutions. |
| Storage instructions | Lyophilized Human Transferrin proteinshould be stored desiccated below -20°C. Upon reconstitution, the protein should be stored at 4°C between 2-7 days and for future use below -20°C. For long term storage it is recommended to add a carrier protein (0.128% HSA or BSA). Please prevent freeze-thaw cycles. |
| Shipping | The product is shipped at ambient temperature. |

| Background | Transferrin (Tf),is an iron transporter, which is mainly biosynthesized in the liver, and it can also be biosynthesized in the brain; i.e., by oligodendrocytes and the choroid plexus, cerebrospinal fluid (CSF) producing tissue. The CSF contains two Tf isoforms, brain-type Tf and serum-type Tf, which differ in their glycan structures. Brain-type Tf is uniquely glycolsylated with biantennary asialo- and agalacto-complex type N-glycans that carry bisecting β1,4-GlcNAc and core α1,6-Fuc.The glycans of serum-type Tf in the CSF are similar to those of Tf in serum. Biochemical analyses reveal that the apparent molecular size of brain-type Tf is smaller than that of serum-type Tf, and that hydrophobic patches are exposed on brain-type Tf as demonstrated by hydrophobic probe binding studies. Research indicates that brain-type Tf levels is decreased in idiopathic normal pressure hydrocephalus, in which CSF production is suspected to decrease, while brain-type Tf increased in spontaneous intracranial hypotension, in which CSF production is suspected to increase. These results suggest that brain-type Tf could be a biomarker of altered CSF production. |

1.The species of antibody reactivity should be the sample species that can be matched normally after Abbkine R&D experts have passed strict scientific verification. If your sample is not within the range of reactivity, in order to improve the efficiency and results of your experiment, it is not suggested to try other species. Otherwise, it may lead to sample mismatch and affect the effect of your experiment.
2.Please aliquot the antibody received as soon as possible and store it at -20℃, avoid repeated freezing and thawing, and use it within one year.
