    DOTATATE acetate purchased from MedChemExpress. Usage Cited in: J Nucl Med. 2024 Oct 1;65(10):1619-1625.  [Abstract]

    Total absorbed dose to cell nucleus for range of added activity concentrations of both 161Tb- and 177Lu-labeled DOTATATE (0-1.25 MBq/mL).

    DOTATATE acetate purchased from MedChemExpress. Usage Cited in: J Nucl Med. 2024 Oct 1;65(10):1619-1625.  [Abstract]

    Radiolabeled DOTATATE (1 MBq/mL) resulted in a higher absorbed dose than did radiolabeled DOTA-LM3, because of DOTATATE's higher Bmax and higher internalization.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
