Ponsegromab
Based on 2 publication(s) in Google Scholar
Ponsegromab is a Growth differentiation factor 15 (GDF15) inhibitor with human, cynomolgus monkey, and mouse target IC50 values of 0.123 nM, 0.053 nM, and 0.102 nM, respectively. Ponsegromab acts as a chemosensitizer, increases intracellular reactive oxygen species, reduces glutathione levels. Ponsegromab can be used for the research of oxaliplatin-resistant colorectal cancer.

Immobilized GDF-15 Protein, Human (P.pastoris, His, HY-P75170) can bind Ponsegromab. The EC50 for this effect is 9.7 ng/mL. -
Flow Cytometry analysis of HepG2 cells with Ponsegromab (HY-P99241, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then cells were stained with the primary antibody at 1/200 dilution for an hour at 4℃. 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).
