FSC(PEG4-αvβ6)₃ 

FSC(PEG4-avb6)₃ is a tracer targeting αvβ6 integrin trimer (IC₅₀ = 0.69 nM). FSC(PEG4-avb6)₃ can be used for the study of head-and-neck, lung, breast, and pancreatic carcinomas^[1].

[⁶⁸Ga]Ga-FSC(PEG4-avb6)₃ exhibits a LogD (pH 7.4) value of -1.4, whereas [⁸⁹Zr]Zr-FSC(PEG4-avb6)₃ shows a LogD (pH 7.4) of -0.9^[1].
[⁶⁸Ga]Ga-FSC(PEG4-avb6)₃ shows specific uptake of 3.9% in H2009 cells, while uptake was negligible in MDA-MB-231 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Ga-FSC(PEG4-avb6)₃ (120-400 pmol, i.v., once) can effectively target H2009 human lung adenocarcinoma cells (αvβ6 positive) tumors in xenograft mice^[1].
