RISC activity was extracted from ribosomes, then fractionated by gel filtration and ion exchange chromatography.

(Caudy et al., 2002)

AGO2, Fmr1 and vig cofractionate as part of the RISC complex.

(Caudy et al., 2002)

Source was cell extract of S2 cell line; proteins produced from endogenous genes.
