Immunoglobulin Genomics in the Guinea Pig Figure 12. The guinea pig Igk locus in scaffold 37. The guinea pig Igk locus is in scaffold 37, the potentially functional Vk gene segments are shown in filled bars, and pseudogenes are represented by open bars. The unidirectional arrowheads below Vk gene segments on scaffold 37 indicate that their transcriptional direction is opposite to downstream Jk segments. Double slashes indicate gaps .10 kb. The scale does not apply the upper frame diagram. doi:10.1371/journal.pone.0039298.g012 Figure 13. The guinea pig Igk locus in scaffold 24. The guinea pig Igk locus is in scaffold 24, the potentially functional Vk gene segments are shown in filled bars, and pseudogenes are represented by open bars. The unidirectional arrowheads below Vk gene segments merely indicate a transcriptional direction different from that of the remaining Vk gene segments in scaffold 24. The scale does not apply the upper frame diagram. doi:10.1371/journal.pone.0039298.g013 PLoS ONE | www.plosone.org 11 June 2012 | Volume 7 | Issue 6 | e39298
