*Optimization of cycle number may be needed based on the total RNA content of the sample. The
ideal target library concentration is 50 - 200 nM. However, if the concentration is between 10-50
nM or between 200-500 nM and if the libraries do not contain low or high molecular weight peaks,
sequencing can still be performed. If optimization is needed, additional Amp Mix can be obtained
using the Fixed RNA Feature Barcode Kit (PN-1000419). For dissociated tumor cells, cycle
numbers for cell lines can be used as a starting point. For dissociated primary cells, cycle numbers
for PBMCs can be used as a starting point.
**For cells derived from the fixed and dissociated tissue samples, the cycle number will depend on
the RNA expression level of the tissue and on overall quality of the tissue prior to fixation.
Additional optimization may be required.
