M701
Based on 1 Customer Validation
M701 is a T-cell engager bispecific humanized antibody targeting epithelial cell adhesion molecule (EpCAM) and cluster of differentiation 3 (CD3). M701 binds to EpCAM on tumor cells and CD3 on T cells, thereby linking the two cell populations to achieve targeted cytotoxicity and T cell-mediated cytotoxicity. M701 is applicable to research related to advanced epithelial solid tumors.

Biological Activity
Bispecific T cell engager antibody
Human
CD3 & EpCAM
M701 (serially diluted concentrations; 1 h) binds to HCT116 colorectal carcinoma cells with a dissociation constant of 32 nM[1].
M701 (serially diluted concentrations; 1 h) binds to human T cells with a dissociation constant of 33.7 nM[1].
M701 (0-10 μg/mL; 30 min) dose-dependently bridges EpCAM-positive NCI-N87 gastric carcinoma cells and CD3-positive CIK cells, reaching up to 40% double-positive cells at 10 μg/mL[1].
M701 (serially diluted concentrations; 24 h) potently redirects CIK cell lysis to EpCAM-high HCT116, NCI-N87, and KATO-III tumor cells with EC50 values of 1.1, 1.8, and 8.5 ng/mL respectively, shows minimal activity against EpCAM-low SK-OV-3 and MDA-MB-231 cells, and has no activity against EpCAM-negative U87 cells[1].
