Upon administration, copper Cu 64-CB-TE1A1P-PEG4-LLP2A targets, binds to and is taken up by VLA-4-expressing tumor cells. Upon PET, the VLA-4-expressing tumor cells can be visualized, and the tumor can be assessed. VLA-4, a transmembrane adhesion receptor overexpressed and activated on various tumor cell types and surrounding stroma, plays an important role in tumor growth, angiogenesis, metastasis, drug resistance and immune responses. Pegylation optimizes the pharmacokinetic profile of 64Cu-LLP2A." @default.
