Anti-Rad18 (human) polyclonal antibody


The Rad6-Rad18 pair of genes plays a critical role in post-replication repair of damaged DNA. Rad6 protein functions as an E2 enzyme and Rad18 as a ubiquitine ligase (E3) which ubiquitinates PCNA. Rad18 recruits translesion DNA polymerases to damaged DNA (ref 1~3).


1) Western blotting (1,000 fold dilution)
2) Indirect immuno-fluorescence staining
3) Immuno-precipitation

The lower thick band is native Rad18 and the upper thin band is mono-ubiquitinated Rad18 protein (ref. 1)
