MC38 syngeneic mouse colon tumor model with hamster anti-mouse PD-1 surrogate J43
“The antitumor activity induced by blocking PD-1 was shown in vivo in mice in a syngeneic tumour model where MC38 colon adenocarcinoma was injected subcutaneously and mice were treated using a commercially available homologous anti-mouse PD-1 monoclonal antibody J43 at 2 mg/kg and 10 mg/kg doses every 3-4 weeks.”
Pembrolizumab does not cross-react with murine PD-1
“Given the lack of cross-reactivity of MK-3475 with murine PD-1, a commercially available hamster anti-murine PD-1 mAb, J43, was used as surrogate for in vivo pharmacology studies.”
