Candidate TAS repeat factor enrichment levels by Western blot assay. (A) Candidate enrichment on PICh-purified protein from S3 cells. Lanes contain 15% of the purified protein and 0.01% input; for Polycomb and dRING, 0.03% and 0.1% input lanes are shown. (B) Negative control and TAS-R purifications from Kc cells. Lanes contain 15% of the purified protein.
