Compared with 1ng condition (Note: using 0.5ul of final 1ng combined library from 12062013): [[File:12102013_PCR2_ERCC-3.jpg]] [[File:12102013_PCR2_ERCC-5.jpg]] [[File:12102013_PCR2_ERCC-30s.jpg]] Results: Can see that the 3' is better represented than the 5' for 10pg. In the 3' analysis it looks like 30s-1min are the better conditions, while in the 5' analysis the 15s-30s appears optimal. Therefore, 30s may represent the universally best condition for 10pg RNA fragmentation. *Combined id89-96 (2ul of each) *Ran 1ul onto gel: [[File:12102013_PCR1_gel2.jpg]]
