Protein Length

Full Length of Mature Protein

Tag Info

N-terminal 10xHis-tagged and C-terminal Myc-tagged

Form

Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.

Buffer

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Troubleshooting and FAQs

Protein FAQs

Storage Condition

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Lead Time

3-7 business days

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

The production of recombinant Human MELTF protein involves manipulating the expression of the desired gene in e.coli cells. The sequence (20-302aa) of foreign DNA is merged with an expression vector and subsequently introduced into e.coli cells. Positive cells are chosen and cultivated to induce the expression of the desired protein. A N-terminal 10xHis tag and C-terminal Myc tag is fused to the protein. The resulting recombinant Human MELTF protein undergoes purification through affinity purification, with a purity exceeding 85%, as confirmed by SDS-PAGE.

Target Background

Function

Involved in iron cellular uptake. Seems to be internalized and then recycled back to the cell membrane. Binds a single atom of iron per subunit. Could also bind zinc.

membrane-bound and soluble p97 affect the migration capacity of endothelial and melanoma cells and suggest that p97 could be involved in the regulation of plasminogen activation by interacting with pro-uPA and plasminogen. PMID: 12750156
Serum melanotransferrin exists in various conformations depending on the binding of bivalent cations or following post-translational modification; serum melanotransferrin levels are unchanged in subjects with Alzheimer's disease. PMID: 12809550
The distribution of MTf and its splice variants may provide clues to their possible biological roles in melanoma and other tumors. PMID: 15716025
melanotransferrin has a role in cell proliferation and tumorigenesis PMID: 16704991
Anti-angiogenic properties of soluble melanotransferrin may result from local overstimulation of plasminogen activation by tissue plasminogen activator, thus leading to subsequent degradation of the fibronectin matrix and endothelial cell detachment. PMID: 16713448
Altogether, these findings strongly suggest that MTf overexpression in melanoma cells contributes to tumor progression by stimulating plasmin generation as well as cell migration and invasion. PMID: 17196552

this review discusses the studies that have demonstrated that melanotransferrin is not involved in iron metabolism, but plays a vital role in melanoma cell proliferation and tumorigenesis. PMID: 17452986
