HemaCare Corporation and Charles River Laboratories International Inc. have formed a strategic partnership to advance human immune system research by developing a more efficient and reliable method of working with humanized mice. HemaCare's peripheral blood mononuclear cells will be integrated into Charles River's NCG/PBMC Select Humanization Kit. This kit is the first of its kind in the industry and provides both the NCG mouse and vials of pre-selected human PBMCs, allowing the researcher to efficiently develop the humanized mouse model.

The key to the creation of humanized mice is the engraftment of human PBMCs, which allows for development of human immune systems. The challenges that researchers often face is that engraftment varies with each PBMC donor. By evaluating human PBMCs from donors in advance, optimal donors can be identified, pre-qualified, and their cells included in the humanized mouse model kit.
