NKG mice (Catalog number: C001316) are a kind of severe immunodeficient mice generated by Cyagen through deleting the Il2rg gene from NOD-Scid mice. NKG mice exhibit deficiency of mature T cells, B cells, and functional NK cells, reduced complement activity, and weak phagocytosis of human-derived cells by macrophages, which are well suited for the transplantation of human hematopoietic stem cells (HSC), peripheral blood mononuclear cells (PBMC), adult stem cells and tissues, and patient-derived xenograft (PDX).

huHSC-NKG mice are immune system humanized mouse models constructed by transplanting human hematopoietic stem cells (HSC) into NKG mice after sub-lethal dose irradiation. This model has a long lifespan and can successfully reconstitute various immune cells. In addition, huHSC-NKG mice typically do not develop graft-versus-host disease (GvHD) and the reconstitution period can be long.

The huHSC-NKG-ProF mouse is the latest enhanced version of the huHSC-NKG series, where "Pro" indicates the enhanced series and "F" indicates full immune reconstitution. This mouse model uses advanced neonatal techniques optimised to develop a variety of human immune cells, including lymphoid T cells, B cells and NK cells, as well as myeloid dendritic cells (DCs), monocytes, macrophages and granulocytes. Due to its ability to reconstitute multiple types of human-derived immune cells, the huHSC-NKG-ProF mouse is also referred to as a fully humanised immune system mouse. It is an ideal model for immunological research, antibody-dependent cellular cytotoxicity (ADCC) studies and the development of tumor vaccines, cellular therapies and other biopharmaceuticals.
