Instrument: Precellys® 24
Sample: Rhizobium etli cell pellets or bacteroid pellets
Samples were analyzed for RNA quality using Experion RNA StdSens Chips (see figure below) and all samples had an RNA quality indicator of 10. Additionally, RNA quantity and purity was assessed using the NanoDrop ND-1000, and both the A260/A280 ratio and A260/A230 ratio for all samples were ≥ 2.
