Fluorescence micrograph showing meiotic configurations visualized by synaptonemal complexes (SCs) at the pachytene stage. The cells were treated with antibodies against SCP3/SYN1 (to visualize SCs; red), MLH1 (to identify meiotic exchanges; green) and with CREST antiserum (to detect centromeric regions; blue). This image is a late pachytene spread. (See Sun et al. pp. 361-364.)
