Why IDT recommend for brief centrifugation, this is because white flakey pellet of oligos at the bottom of the tube can become dislodged during shipping, it is crucial to briefly centrifuge every oligo before opening the tube. Failure to do so could result in yield loss, because oligo pellets that are not at the bottom of the tube could fly out of the tube when the cap is opened.
Mostafa Kamal Masud thank you for responding. I understand the reasons behind the requirement of centrifugation prior to suspension. I was confused about the required speed.
