Summary of protocols used in experiments 2 and 3. Cost is estimated per sample assuming a large number of libraries at US catalog prices as of May 2014, and includes RNA extraction.
Protocol Shorthand Cost/library
TruSeq TruS $45
Clontech CT $105
TotalScript TotS $115
Smart-seq2, standard protocol SS $55
Smart-seq2, 2.5 fold dilution SS—2.5x $28
Smart-seq2, 5 fold dilution SS—5x $20

\label{tab:protocolcosts}

Sequencing summary statistics for samples. Protocols are the shorthands used in table \ref{tab:protocolcosts}. Reads indicates the total number of reads, and Mapped the total number of reads that mapped at least once to either genome. Experiments 2 and 3 were run in a single HiSeq lane each.
