Oligo Synthesis FAQs

1. What’s your turn around time for oligos?

a. For oligos less than 35 bases without modifications or purifications, if you place your order online by 5pm PST, your oligos will be ready the next day.
b. For oligos that are longer than 35 bases, or oligos requiring modifications or purifications, it generally takes one additional day.

2. What are your length limits for your oligo scales?

iii. 200nmol up to 80bp
iv. 1umol for greater than 80bp.
