+Short structured RNAs with low GC content are selectively lost during extraction from a small number of cells.

+[[!pmid 22749402 desc="In extraction methods using Trizol, the long RNAs present in the cell lysate
+act as carrier for the short RNAs, and when initial cell numbers are low or magnesium ions
+are chelated, structured small RNAs become selectively harder to capture, which causes
+a bias that can be confounded with key experimental parameters."]]
