- The B-NDG mouse is a perfect tool for immune system humanization and patient derived xenograft transplantation
- The B-NDG mice (NOD-Prkdcscid Il2rgtm1/Bcgen), independently developed by Biocytogen, display a severe immunodeficiency phenotype, with no mature T, B or functional NK cells, and deficient in cytokine signaling. The B-NDG mouse is one of the best models for reconstitution of human immune system using peripheral blood mononuclear cells (PBMC) or hematopoietic stem cells (CD34+).
- Humanized knock-in mouse models for evaluating in vivo efficacy of immune-oncology drugs targeting inhibitory immune checkpoint molecules
- In most cases, a human monoclonal antibody does not have mouse cross-reactivity. Therefore, we generated humanized knock-in mouse to evaluate the in vivo efficacy of human IO antibodies. For example, human PD-1 knock-in (B-hPD-1) mice were generated with a chimeric PD-1 receptor, which is recognizable by human PD-1 antibodies, and can be used to test human PD-1 antibody in vivo efficacy.
