SHR-A1403 Antibody
SHR-A1403 Antibody is an anti-c-Met monoclonal antibody. SHR-A1403 Antibody down-regulates phosphorylated c-Met, Akt, ERK, weakens intracellular signal cascades, and mediates antibody-c-Met complex endocytosis. SHR-A1403 Antibody can be used for the research of c-met-overexpressing cancers and pancreatic ductal adenocarcinoma.
For research use only. We do not sell to patients.

SHR-A1403 Antibody (SHR-A1403 mAb) binds with high affinity to human and cynomolgus monkey c-Met (Kd values of 1.58 × 10-8 M and 2.84 × 10-8 M, respectively) and does not bind mouse c-Met[1].
SHR-A1403 Antibody has low to no binding affinity to human Fc receptors and complement C1q, with measurable low affinity only for FcRn, FcγR I/CD64, and FcγR III/CD16[1].
SHR-A1403 Antibody (72 h) minimally inhibits proliferation of NCI-H1993, NCI-H441, A549, MKN-45, NCI-N87, Hs578T, PC-3, Caki-1, and HCCLM3 human cancer cell lines, with IC50 values greater than 5000 ng/mL[1].
SHR-A1403 Antibody (1 h) binds to human gastric cancer MKN-45 cells in a dose dependent manner[1].
SHR-A1403 Antibody (10-10000 ng/mL; 24 h) dose-dependently inhibits c-Met downstream signaling in human gastric cancer MKN-45 cells, reducing phosphorylated c-Met, Akt, and ERK levels[1].
SHR-A1403 Antibody (10 μg/mL; 1 h) is time-dependently internalized into human gastric cancer MKN-45 cells, reaching an endocytosis rate of ~30% after 3 h of incubation at 37 °C[1].
SHR-A1403 Antibody (1 μg/mL; 23 h) translocates to lysosomes in human gastric cancer MKN-45 cells[1].
SHR-A1403 Antibody (4 h) exhibits no detectable ADCC activity against human gastric cancer MKN-45 cells[1].
SHR-A1403 Antibody (15 min) exhibits low CDC activity against human gastric cancer MKN-45 cells[1].
