Fig. 1. Detection of Rad18Sc protein. (A) On an immunoblot of proteins isolated from total testis lysate, the anti-Rad18Sc antibody recognizes a specific protein band around 80 kDa (arrowhead). (B) In vitro transcription-translation using Rad18Sc cDNA results in a protein band with a molecular mass of approximately 80 kDa (arrowhead).
