Immune Humanized Mouse Models

Humanized NSG mice are a therapeutically translational platform for the evaluation of human immune cells in vivo, the evaluation of single and combinatorial drug approaches, and the production of predictive data for the clinic. These models can be used in immuno-oncology applications, stem cell biology, and therapeutic efficacy/toxicity testing. With thousands of publications, The Jackson Laboratory's Humanized NSG Platform is your partner for translational research.

CD34+ Humanized Mouse Model Comparison

Produced by engraftment of human cord blood derived hematopoietic stem cells (HSCs), these models yield stable multilineage immune cell development and enable long-term longitudinal studies. Customization and CD34+ HSC engraftment of other NSG and NRG variants are also available.

Confidently Evaluate Your Therapies In The Humanized NSG Platform

CD34+ Humanized NSG and NSG variant mice are ready to ship 8-12 weeks following engraftment. With our guarantees of at least 25% CD45 engraftment, researchers can be confident in the abundance of human immune cells for their therapeutic study. CD3+ T cells are a critical cell of interest in immuno-oncology and our off-the-shelf Humanized NSG mice produce high and stable levels of CD3+ T cells following engraftment.
