Human Lambda Light Chain Mice |
摘要 |
Genetically modified mice are provided that express human λ variable (hVλ) sequences, including mice that express hVλ sequences from an endogenous mouse λ light chain locus, mice that express hVλ sequences from an endogenous mouse κ light chain locus, and mice that express hVλ sequences from a transgene or an episome wherein the hVλ sequence is linked to a mouse constant sequence. Mice are provided that are a source of somatically mutated human λ variable sequences useful for making antigen-binding proteins. Compositions and methods for making antigen-binding proteins that comprise human λ variable sequences, including human antibodies, are provided. |

1. A transgenic mouse comprising in its genome an endogenous λ light chain immunoglobulin locus comprising a deletion of the endogenous mouse Vλ1-Jλ3-Cλ3-Jλ1-Cλ1 gene cluster and a deletion of a region spanning from Vλ2 to Jλ2 of the endogenous mouse Vλ2-Vλ3-Jλ2-Cλ2-Jλ4-Cλ4 gene cluster. |
