Rabbit Anti-Human Argonaute 1 monoclonal antibody for KnockDown (KD), WB. AGO1 is a member of the Argonaute family of proteins which play a role in RNA interference. The protein is highly basic, and contains a PAZ domain and a PIWI domain. It may interact with dicer1 and play a role in short-interfering-RNA-mediated gene silencing. AGO1 binds to miRNAs or siRNAs and represses the translation of mRNAs.
