Example Calculation
A 101-cycle dual-indexed paired-end run has a total of 225 cycles:
u
124 cycles (101 + 8 + 7 + 8) for Read 1 and the Index Reads
u
101 cycles for Read 2
Read 1 and Index Reads (124 Cycles)
Read 2 (101 Cycles)
124 cycles / 10 cycles = 12.4
• ICB: 12.4 x 4.57 ml = 56.9 ml
• LFN: 12.4 x 0.6 ml = 7.44 ml
• EDP: 12.4 x 0.11 ml = 1.36 ml
101 cycles / 10 cycles = 10
• ICB: 10 x 4.57 ml = 45.7 ml
• LFN: 10 x 0.6 ml = 6 ml
• EDP: 10 x 0.11 ml = 1.1 ml
Use the same calculation for any dual-indexed run. Base the calculation on the total number of cycles in
Read 1 and the Index Reads plus the total number of cycles in Read 2. For dual-indexed paired-end runs,
include the 7 chemistry-only cycles in the Index 2 Read.
Prepare Indexing Reagents
Indexing reagents are used during the indexing reads of an indexed sequencing run. Prepare the reagents
that are appropriate for the run type and library type.
