Performance data

Yield

Get reliable yields at every prep scale, backed by fluorometric quantification.

Items meeting advertised minimum yield — Micro 98.6%, Mini 98.2%, Midi 99.9%, Maxi 99.1%.

Turnaround time

Keep projects moving with predictable timelines on every order, regardless of scale, complexity or sequence length.

Microprep turnaround time — Express: 6.1 business days average, 5 median; Standard: 9.4 average, 9 median.

Success rate

Every DNA order is routine and reliable, with 98.4% manufacturing success on low and medium complexity sequences. Genes only leave the factory when NGS verified as a 100% match to your desired sequence.

Clonal gene manufacturing success rate — 98.4% Low/Medium complexity, 94.7% High complexity shipped.

SpecificationValueDetails
Product format Circular dsDNA
Length 0.3 kb – 7.0 kb
Complexity Low | Medium | High

A sequence’s complexity score is based on the combined presence, frequency, and length of various features within the design of a sequence. Impacts the ease and speed of production.

High complexity sequences are produced though a series of specialized manufacturing workflows. Supported features include:

  • Short tandem repeats: 3–9bp repeats in up to 100bp stretches
  • Long repeats: repeats up to 200bp
  • Inverted (palindromic) repeats: up to 100bp
  • Localized GC extremes: 10–90% within a 50bp window
  • Sequence-wide GC extremes: 25–75%
  • Stable secondary structures: hairpins, G-quadruplexes
Codon optimization 100s of target organisms Large language model-driven for protein expression.

*This timeframe refers to the typical processing and handling time within our facilities before your order is handed over the shipping carrier. Gene Fragments are shipped in 2-4 business days. Eligible Express Genes ship in 4-7 business days. Average turnaround time for Clonal Genes is 10 business days. Our target completion timeline for clonal genes scored as complex is 15 business days. Turnaround time for Clonal Genes is subject to change based on customizations and sequence complexity. New vector onboarding for Clonal Genes will add additional turnaround time. Orders placed outside of the US will incur additional delivery time.
