Ready-to-use ELISA kits are available for the detection of argonaute RISC catalytic subunit 1, an alias of the protein, argonaute RISC component 1. The official gene symbol is AGO1. The protein, with a mass of 97.2 kDa and length of 857 residues, is reported to be cytoplasmic. It is a member of the Argonaute family, Ago subfamily and may be known by other names, including: eIF2C 1, eIF-2C 1, argonaute RISC catalytic component 1, argonaute 1 RISC catalytic component, Golgi Endoplasmic Reticulum protein 95 kDa, and protein argonaute-1, and putative RNA-binding protein Q99.
