Mirvetuximab (0.17 pM-81 nM, 2 h) bounds three antibodies bound with high affinity, with EC50 values in the double-digit picomolar range (14.3, 16.5, and 21.1 pM for binding to clones 4E12-G5, 4E12-B9, and 5D12-C11, respectively)[2].
Mirvetuximab (1 pM-100 nM) shows dose-dependent binding to folate receptor in the absence of competing anti-idiotype antibodies[2].
M9346A (1 pM-100 nM) associates with H2110 cells with an EC50 of around 650 pM by specific binding of M9346A to surface folate receptor antigen[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Flow cytometric analysis of 1X106 MCF-7 cells with Mirvetuximab (HY-P99225, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black). -
