Figure 5. Jκ and Jλ germline transcription and PTMs in μ⁺ RAG^−/− cells, RAG^−/−, mb1^−/− and μMT pro-B cells.

A. Transcript levels of Jκ and Jλ loci in pre-B cells from μ⁺RAG^−/− mice or in pro-B cells from RAG^−/− or μMT mice. The level of each GT is plotted relative to the level in μ⁺RAG^−/− pre-B cells. B. PTMs patterns on Ig κ and λ genes in pre-B cells from μ⁺RAG^−/− mice or in pro-B cells from RAG^−/−, μMT or mb1^−/− mice.
