GSM1154018: total scnRNAs from TWI1 KO cells; Tetrahymena thermophila; RNA-Seq
Wild-type Tetrahymena thermophila strains B2086 and CU428 and the complete TWI1 KO strains (Mochizuki and Gorovsky 2004) were used for total RNA preparation. Twi1p was immunoprecipitated (Noto et al. 2010) from either wild-type cells using an anti-Twi1p antibody (Noto et al. 2010) or from the strains expressing HA-Twi1p and HA-Twi1p-hAGO2Lmut (Mochizuki and Kurth in press) using an anti-HA antibody (16B12, Covance). The cDNA libraries were constructed as described (Schoeberl et al. 2012). For multiplex sequencing, oligonucleotides listed below were used. Single-read 36- or 50-base sequences were generated using the Illumina GAII or HiSeq2000, respectively. Sequence reads were filtered as described (Schoeberl et al. 2012).
