Custom E. coli strain and pathway engineering programs scoped around your target molecule, host background and assay needs.
We engineer E. coli strains for target compound production and protein expression, with design, construction, confirmation and small-scale evaluation organised as one project.
Every program starts from your target molecule, the host background you want to use and the readout your team will assess, then moves through design, build, confirmation and evaluation.
E. coli is our working production host, and the strain background is confirmed with you before design starts, because host choice frames the design space available for the target route.
Design proposals set out the genetic changes intended for the strain, including the target route and supporting modifications, and are reviewed with your team before any construction begins.
Engineered strains are screened and confirmed at the sequence level so that the strains carried forward match the approved design.
Product and by-product measurement is agreed at scoping and carried out with methods suited to the target molecule and sample type.
Project records, sequence information and datasets are assembled so your team can continue work with the strains after delivery.
Handoff items, including strain materials and data, are confirmed in the project scope.
Scope is agreed case by case in the project plan, and the table below shows the parameters typically discussed before work begins.
| Parameter | Typical project scope |
|---|---|
| Host and strain background | E. coli strain background selected with your team based on the target pathway and product; final choice confirmed at scoping. |
| Target molecule and route | Defined from the customer-supplied target compound, precursor context and any known route constraints discussed at scoping. |
| Pathway design scope | Genetic changes proposed for the strain, reviewed and approved by the customer before construction starts. |
| Editing modality | Knockout-based edits as the primary approach; knock-in and other precise edits are evaluated case by case. |
| Strain build depth | Number of strains and design iterations delivered within the program is defined in the project scope. |
| Genotype confirmation | Colony-level screening and sequence-level confirmation of the intended edits in the strains released to you. |
| Evaluation format | Small-scale evaluation as standard; larger-scale work scoped separately, with readouts and sample handling agreed at scoping. |
| Analytics | Product and by-product measurement using methods agreed at scoping for the target molecule and sample type. |
| Controls | Parent or control strains included when the agreed scope calls for a comparison baseline. |
| Data package | Sequence documentation, screening datasets and a final report delivered in the format agreed with your team. |
| Technical support | Named scientific contact at project start; milestone review calls; email response within 1 business day |
A five-stage engagement keeps design decisions visible and places confirmation and evaluation ahead of delivery.
We agree the target molecule, the E. coli host context, the readout your team will assess and the acceptance criteria for the program before any design work begins.
A design proposal sets out the intended genetic changes and supporting modifications for the target route, and your team reviews it before construction starts.
Approved designs are built in the agreed E. coli background, with intermediate construct checks and strain records kept as the program progresses.
Candidate strains are screened and confirmed at the sequence level so that the strains carried forward match the approved design rather than a partial edit.
Selected strains are evaluated against the agreed readouts, and strain stocks, datasets and documentation are assembled for delivery to your team.
These are common starting points for customer projects; the route, host context and readouts are always fixed during scoping.
Programs aimed at producing a defined chemical or intermediate in E. coli, where the customer needs a strain that carries an introduced or modified production route.
Strain engineering for amino acid and specialty molecule targets, where customer-supplied specifications guide the pathway design and the evaluation criteria used.
E. coli strain work in support of protein or enzyme expression projects, where the customer defines the expression context and the readouts that matter to the next stage.
These answers cover the practical points customers raise when planning an E. coli metabolic engineering program with us.
Design is proposed by our team and reviewed with yours before construction starts. Each intended genetic change is described in the design proposal together with its rationale, so design choices stay visible and any change to the plan is agreed rather than assumed.
Knockout-based edits are our primary modality and the default starting point for most strain programs. Knock-in and other precise edits can be evaluated case by case during design review, and the modality used for your project is written into the agreed scope.
Handoff is defined in the project scope and typically includes engineered strain stocks, construct and sequence documentation, screening and confirmation datasets, analytics results for the agreed readouts, and a final report. Items not in scope are confirmed with you before they are added.
Yes. Host and strain background are confirmed at scoping, and an existing strain can be reviewed as the starting point where it suits the target route. Where the current background limits the design space, we will discuss alternatives with you before the plan is fixed.
Named scientific contact at project start; milestone review calls.
Small-scale evaluation is the standard format offered within an engineering program, and larger-scale work is scoped separately when your project requires it. The evaluation format, readouts and sample handling are agreed with you at scoping rather than assumed.
