Product Description |
Recombinant Human CD228/MFI2 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gly20-Cys709. |
Product Background |
Melanotransferrin is typically overexpressed in melanoma cells compared to other cell types - including cancer cells - and is efficiently sorted and secreted with nanovesicles, or so-called exosomes, due to its membrane-anchoring by a glycosylphosphatidylinositol. Melanotransferrin is exposed on the surface of exosomes and is accessible for antibody recognition. |

Amino Acid Range |
Gly20-Cys709 |
Molecular Weight |
The protein has a predicted MW of 76.60 kDa. Due to glycosylation, the protein migrates to 78-88 kDa based on Bis-Tris PAGE result. |
