GenScript, on its own published figures
GenScript publishes two prices for the same job on its Gene Synthesis page: an entry rate per base pair, and a flat rate per construct that its own wording says includes cloning and plasmid preparation. Both were fetched and matched word for word on the date shown. Having both models from one vendor makes it the clearest illustration in this index of why a per-base headline is a poor single comparison.

GenScript service range, evidenced
GenScript maintains its own service pages for the 2 classes this index tracks; each link below is the vendor's live page for that class, which is the evidence this site counts as coverage.
How GenScript prices its range
The flat-rate construct price bundles synthesis, cloning and a plasmid preparation into one number, which is why it sits so far above the per-base entry rate and why the two are not alternatives so much as different ways of buying. For a construct of ordinary length needing a usable plasmid, the flat rate is frequently the cheaper of the two once the separate lines are added up.
GenScript also publishes more than one per-base rate, which is the complexity tiering other vendors apply at quotation made visible on the page. The figure recorded here is the entry rate; the higher published rate applies to more difficult sequences.
Common questions
- What does GenScript charge for gene synthesis?
- Its advertised entry rate per base pair and its flat rate per construct are both shown in the facts table, quoted verbatim from its own Gene Synthesis page with the retrieval date.
- What does the GenScript flat rate include?
- Its own page states the flat-rate construct price includes cloning and plasmid preparation. That quote is reproduced in the facts table so you can check the wording yourself.
- Which GenScript price applies to my sequence?
- The entry rate assumes standard complexity. GenScript publishes a higher per-base rate for more difficult sequences, so a high-GC or repetitive construct should be quoted rather than costed from the entry figure.
