Can NextSeq 1000/2000 custom primers be diluted in in RSB with Tween instead of HT1?

Custom sequencing primers for the NextSeq 1000/2000 must be diluted in HT1, per the NextSeq 1000/2000 Product Documentation Custom Primers Prepare and Add Custom Primers. HT1 must either be purchased separately (cat. 20015892) or purchased bundled in the NextSeq 1000/2000 primer kits, listed below:

• NextSeq 1000/2000 XLEAP-SBS Read and Index Primers (cat. 20112856)

• NextSeq 1000/2000 XLEAP-SBS Index Primer Kit (cat. 20112858)

• NextSeq 1000/2000 XLEAP-SBS Read Primer Kit (cat. 20112859)

Custom primers diluted in RSB-Tween, rather than HT1, have been observed to cause cycle 1 failures.
