A humanized immune system (HIS) mouse designed for more accurate assessment of antibody-based drugs


Nomenclature: NOD.Cg-Fcgr2btm1Ttk Fcer1gtm1Rav Prkdcscid Il2rgtm1Sug

  • The FcResolv™ huNOG is a HIS mouse made by engrafting hematopoietic stem cells (HSCs) in the FcResolv NOG strain.
  • Made to order, with typical lead time of 20 weeks from order to delivery. Minimum purchase required.
  • Human lymphocytes are present in peripheral blood, bone marrow and spleen.
  • All mice shipped meet a QC spec of ≥25% hCD45+ in peripheral blood as assessed at 12 weeks post-engraftment.
  • Long-term studies are possible in huNOG mice, with literature reports of stable engraftment and hematopoiesis for one year or more, and similar study windows are expected in FcResolv huNOG mice. However, not all human immune cell types are present, and some cell types may not be completely functional.
  • 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.

FcResolv NOG Characteristics

  • The FcResolv NOG is a super immunodeficient NOG mouse that has a further reduction in residual murine immune activity via ablation of mouse Fc gamma receptors (FcγRs) to improve accuracy of results.
  • Murine FcγRs can confound experiments in several ways, leading to false positive or negative results. Removing murine FcγRs provides improved accuracy for efficacy assessment of antibody-based therapies which include an Fc domain.
  • Lacks all murine Fcγ receptors, including the FcγRI, IIB, III and IV types, along with the high affinity FcεRI receptor. The low affinity FcεRII receptor remains present.
  • FcResolv NOG mice support higher average levels of human cells following engraftment with HSCs compared to the base NOG mouse; human cell frequencies may vary somewhat between the two humanized models.
Orders by weight: Taconic cannot accept orders by weight for this model. Please note that shipments may contain animals with a larger weight variation.
