Fig. 1. Co-localization of JIL-1 with Chromator at polytene chromosome bands. Double labeling of a female polytene chromosome squash preparation with antibodies against JIL-1 (B) and Chromator (C). The composite image (A) shows the extensive overlap between JIL-1 (green) and Chromator (red) labeling at a large number of chromosome bands as indicated by the predominantly yellow color. The images are from confocal sections.
