Gene Synthesis 3–5 kb
Sequences between 3 and 5 kb push the limits of standard gene fragment services. Fewer providers cover this range, and prices tend to be higher. Here is a comparison for a representative 4000 bp sequence.

| ENFINIA linear DNA | $280.00 | $0.070 | 6–8 business days | 1,000–7,000 bp | Yes | |
| Clonal gene | $360.00 | $0.090 | 4–10 business days | 300–5,000 bp | Yes | |
| ENFINIA plasmid DNA | $480.00 | $0.120 | 6–8 business days | 1,000–15,000 bp | Yes | |

Which providers can synthesise genes between 3 and 5 kb?
Twist Bioscience supports fragments and clonal genes up to 5 kb. Elegen offers linear and plasmid DNA up to 7 kb and 15 kb respectively. Most other fragment providers cap at 1.5–3 kb.
Is long gene synthesis more expensive per base pair?
Not necessarily for per-bp priced products. Twist and Elegen charge the same per-bp rate regardless of length within their supported range. However, complexity-related surcharges are more common for longer sequences due to repetitive regions and secondary structures.
