AGO expression may be cell/tissue specific and using floral tissue is recommended where most of the AGOs are expressed the highest. Seedlings can be used as a negative control. Use of proteasome inhibitors as MG132 can help to stabilize AGO proteins during extraction procedure.A recommended whole-mount immunolocalization protocol can be found here.
AGO9 belongs to a group of argonaute proteins that are catalytic components of the RNA-including Silencing complex (RISC).
