Ladiratuzumab
Based on 1 Customer Validation
Ladiratuzumab (hLIV22) is a humanized monoclonal antibody against zinc transporter LIV-1/ZIP6. Ladiratuzumab is conjugated to MMAE (HY-15162) via a cleavable dipeptide linker to synthesize an antibody-drug conjugate (ADC) Ladiratuzumab vedotin (HY-P99683). Ladiratuzumab vedotin selectively targets LIV-1 protein overexpressed on the surface of tumor cells, enters cells through antibody-mediated receptor endocytosis, releases MMAE to inhibit microtubule polymerization, and kills adjacent tumor cells with a bystander effect. Ladiratuzumab can be used in the study of solid tumors such as metastatic triple-negative breast cancer (mTNBC).

LIV-1/SLC39A6
In Vitro
Ladiratuzumab ADC molecule, Ladiratuzumab vedotin (SGN-LIV1A), induces microtubule network disruption and inhibited cell growth in MCF-7 and BR0555 breast cancer cell line experiments, showing antigen-specific cytotoxicity[1].
LIV-1 is a transmembrane protein and an estrogen-induced gene in breast cancer cells. Ladiratuzumab vedotin inhibits cell proliferation in LIV-1-positive breast cancer cells in vitro in a dose-dependent manner and has anti-tumor activity targeting LIV-1[1][2].

Immobilized LIV-1/SLC39A6 Protein, Human (HEK293, HY-P78749) can bind Ladiratuzumab. The ED50 for this effect is 2.230 ng/mL. -
Flow cytometric analysis of 1X106 MCF-7 cells labeling SLC39A6 with Ladiratuzumab (HY-P99682, red). Cells were stained with the primary antibody at 1/200 dilution for an hour at 4℃. AF488-conjugated 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 Isotype Control (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
