Anti-AGO2 | Argonaute 2

AGO2 belongs to a group of argonaute proteins which are catalytic component of the RNA-incudes silencing complex (RISC) . This protein complex is responsible for the gene silencing (RNAi) . AGO2 is probably involved in antiviral RNA silencing.

AGO2 protein is strongly induced by stress.AGO expression may be tissue specific and using floral tissue is recommended where most of the AGOs are expressed the highest. Use of proteasome inhibitors as MG132 can help to stabilize AGO proteins during extraction procedure.Antibody incubation should be done over night in 4°C. Use of material with enriched AGO2 levels is recommened.

Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
