Ready-to-use ELISA kits are available for the detection of argonaute RISC catalytic subunit 2, an alias of the protein, argonaute RISC catalytic component 2. The official gene symbol is AGO2. The protein, with a mass of 97.2 kDa and length of 859 residues, is reported to be cytoplasmic and nuclear. It is a member of the Argonaute family, Ago subfamily and may be known by other names, including: long intergenic non-protein coding RNA 980, eukaryotic translation initiation factor 2C 2, cancer susceptibility candidate 7, argonaute 2 RISC catalytic component, PAZ Piwi domain protein, and protein argonaute-2, and CASC7.
