## 3.3 GEX Adaptor Ligation
- a. Prepare Adaptor Ligation Mix. Pipette mix and centrifuge briefly.
- b. Add 50 μl Adaptor Ligation Mix to 50 μl sample. Pipette mix 15x (pipette set to 90 μl). Centrifuge briefly.
- c. Incubate in a thermal cycler with the following protocol.

## 3.4 GEX Post Ligation Cleanup - SPRIselect
- a. Vortex to resuspend SPRIselect Reagent. Add 80 μl SPRIselect Reagent (0.8X) to each sample. Pipette mix 15x (pipette set to 150 μl).
- b. Incubate 5 min at room temperature .
- c. Place on the magnet· High until the solution clears.
- d. Remove the supernatant.
- e. Add 200 μl 80% ethanol to the pellet. Wait 30 sec .
- f. Remove the ethanol.
- g. Repeat steps e and f for a total of 2 washes.
- h. Centrifuge briefly. Place on the magnet· Low .
- i. Remove any remaining ethanol. Air dry for 2 min . DO NOT exceed 2 min as this will decrease elution efficiency.
- j. Remove from the magnet. Add 30.5 μl Buffer EB. Pipette mix 15x.
- k. Incubate 2 min at room temperature .
- l. Place on the magnet· Low until the solution clears.
- m. Transfer 30 μl sample to a new tube strip.

<!-- image -->
- a. Choose the appropriate sample index sets to ensure that no sample indices overlap in a multiplexed sequencing run. Record the 10x sample index name (PN-3000431 Dual Index Plate TT Set A well ID) used.
- b. Add 50 μl Library Amp Mix (PN-2000531) or Amp Mix (PN2000047/2000103) to 30 μl sample.
- c. Add 20 μl of an individual Dual Index TT Set A to each sample and record the well ID used. Pipette mix 5x (pipette set to 90 μl). Centrifuge briefly.
- d. Incubate in a thermal cycler with the following protocol.
| Lid Temperature | Reaction Volume | Run Time |
|-------------------|-----------------------------------------|---------------|
| 105°C | 100 μ l | ~30 min |
| Step | Temperature | Time hh:mm:ss |
| 1 | 98°C | 00:00:45 |
| 2 | 98°C | 00:00:20 |
| 3 | 54°C | 00:00:30 |
| 4 | 72°C | 00:00:20 |
| 5 | Go to step 2, see below for # of cycles | |
| 6 | 72°C | 00:01:00 |
| 7 | 4°C | Hold |
The table recommends a starting point for optimization. The total cycles should be optimized based on 25% carry forward cDNA yield/input calculated during cDNA QC &amp; Quantification (step 2.4).
## Recommended Cycle Numbers
