Biological Activity

Description Pembrolizumab (anti-PD-1) is a potent, highly selective, fully humanized immunoglobulin (Ig) G4-kappa monoclonal antibody against PD-1 with potential immune checkpoint inhibitory and antineoplastic activities. MW : 146.286 KD.
Targets
PD-1 [1]
(Cell-free assay)
In vitro

The level of LDH and apoptosis are significantly higher in those treated with dexamethasone plus PD1 inhibitor pembrolizumab than other groups.[1]
In vivo

Pembrolizumab and dexamethasone synergistically suppress tumor growth of pancreatic cancer in vivo.[1]

Protocol (Only for Reference)

Cell Assay:

  • Cancer cells were incubated with dexamethasone for 48 h followed by co-cultured with PBMCs with effector/target ratio of 10:1 and the addition of PD1 inhibitor (pembrolizumab; 5 μg/mL) for another 48 h. LDH level was detected.
Animal Study:

  • Animal Models: Immune reconstituted NOD/SCID mice model
    Dosages: 5 mg/kg
    Administration: i.v.
    Reference: [1]
