Twist's oligo pools are a user-designed collection of single stranded DNA oligonucleotides, ranging from 20 - 300 nt in length. The oligo pools are synthesized at high uniformity, with >90% of sequences present at signals within 2.5x of the mean, ensuring high uniformity and low dropout rate.

Additionally, industry-leading error rate of 1:3000 ensures the sequences that are ordered is what is delivered.
