  • B2m-NOG mice are engrafted with human peripheral blood mononuclear cells (PBMCs) upon order and shipped within one week of injection.
  • The B2m-NOG is an immunodeficient CIEA NOG mouse® with an additional knockout of the B2m gene which disrupts MHC class I antigen presentation.
  • B2m-NOG mice can successfully engraft human PBMCs and tumors.
  • Compared to NOG, B2m-NOG mice have markedly delayed GvHD onset after human PBMC engraftment, providing an expanded study window (8+ weeks). This vastly increases the utility of the model in immuno-oncology experiments.
  • B2m-NOG has reduced efficiency of human PBMC engraftment relative to NOG as well as a CD4+ bias that increases over time in engrafted peripheral blood T cells (see data in phenotype section).
  • By default, Taconic does not typically utilize myeloablation prior to PBMC engraftment as it can shorten the study window. If desired, inquire about options such as irradiation, PBMCs of specific donor HLA types or patient-derived PBMCs.
  • Humanized immune system mice require special housing and husbandry. We recommend reviewing the the comprehensive document Taconic's Humanized Immune System Models: Licensing, Care & Resources and the Video: Care of HIS mice for experimental success prior to ordering.
Orders by weight: Taconic cannot accept orders by weight for this model. Please note that shipments may contain animals with a larger weight variation.

B2m-NOG mice successfully engraft human PBMCs

PBMC engraftment in NOG-B2m

B2m-NOG mice at 6-11 weeks of age were engrafted with varying doses of human PBMCs via tail vein injection. Engraftment was assessed weekly by flow cytometry of peripheral blood samples and is expressed as human CD3/mouse CD45.

B2m-NOG mice have extended survival following human PBMC engraftment

GvHD-free survival of PBMC engrafted mouse strains

NOG and B2m-NOG mice at 6-11 weeks of age were engrafted with 1 x 107 human PBMCs from a single donor via tail vein injection. Mice were monitored for signs of xenogeneic Graft vs. Host Disease for up to 8 weeks post engraftment. Data is shown in the Kaplan-Meier survival curve to represent proportion of mice exhibiting xenogeneic GvHD-free survival for the study duration by group (N=6/cohort). (P<0.001, Log rank Mantel-Cox test).

T cell subsets in B2m-NOG mice engrafted with human PBMCs

B2m-NOG mice at 6-11 weeks of age were engrafted with 1 x 107 human PBMCs from a single donor via tail vein injection. Peripheral blood samples were collected weekly and immunophenotyped for T cells (CD3) and T cell subsets (CD4, CD8) to assess of T cell subset development and kinetics. Flow cytometry was used to assess CD4 and CD8 T cell subsets across groups. Results represent the average ± SD (N=5-6/cohort).
