Can I order oligos shorter than 5 bases in length?

The shortest catalog oligo IDT can synthesize is 5 bases in length. However, IDT will review requests for shorter oligos. Send an email detailing what you want in terms of sequence, scale, purity, etc. to and it will be reviewed by our non-catalog requests committee. Note that this review takes approximately one week.
