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 method for cloning a λ light chain variable domain, comprising the steps of:
(a) obtaining a cell from a transgenic mouse whose genome comprises an immunoglobulin locus comprising human Vλ and Jλ gene segments operably linked to a mouse Cκ gene such that the mouse expresses an immunoglobulin light chain that comprises a human λ variable domain derived from the Vλ and Jλ gene segments fused with a mouse κ constant domain; and (b) cloning the λ light chain variable domain derived from the human Vλ and Jλ gene segments. |
