Strain Name: NOD/ShiLtJGpt-Prkdc em26Cd52 Il2rg em26Cd52 B2m em1Cd4 /Gpt

Strain Type: Knock-out

Strain ID: T004670

Background: NOD/ShiLtJGpt



NCG mice carry mutations in Prkdc and Il2rg gene in NOD/ShiLtJGpt genetic background. Mutations in the Prkdc gene result in impaired VDJ recombination and the loss of mature T and B cells. The gamma chain of Il2 receptor is a co-receptor subunit of IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21, which are important immune functions, after knocking out the IL2rg gene, the immune function of the mouse is seriously reduced, especially the activity of NK cells is almost lost. B2m, alias Ly-m11, beta2m, beta2-m, β2-microglobulin, is an essential component for the transport of MHC class I proteins to the cell surface. The B2m knockout homozygous mouse cell surface has almost no expression of MHC class I protein, and also have the following characteristics: NK cell deficiency, NK+ T cell deficiency, and decreased serum Ig levels.


1. Human immune system reconstitution (HSC, PBMC)

MHCI expression level detection


An anti-H2K antibody was used to stain the splenocytes from NCG and NCG-B2m KO mice, 59.3% of CD45+ cells from NCG control mice were H2K+, while splenocytes from NCG-B2m KO mice were H2K-.
