C. elegans Transgenic Services

Our lab is fully-equipped and staffed, and continuing to operate as usual.

To say we live in interesting times is an understatement. To put it bluntly, things are not normal out there. COVID-19 is impacting every lab and researcher. We want to be as flexible as we can and provide as much support as we can to accommodate your research.

You can ALWAYS rely on us for:

  • cryopreservation services INCLUDED with all Full Build packages;
  • flexibility in payment terms to accommodate ANY unique situation;
  • flexibility in shipping and delivery to accommodate your schedule.

InVivo Biosystems is a licensed CRISPR Gene Editing solutions provider.

We design, construct, and deliver custom reagents or genetically edited C. elegans optimized to your specifications. We also collaborate on project design to ensure transparency in the genome editing process and guarantee that you receive the transgenic organisms best suited for your experiments.

InVivo Biosystems has successfully delivered 2,500 C. elegans transgenic lines to researchers who rely on our genome-edited strains to generate data and publish results. View publications.

As an expert in C. elegans genome editing, we have developed many unique internal processes to ensure the quality of the strains, including plasmic validation, injection protocol, and to improve our editing efficiency.

Choices of genome editing methods are CRISPR, MosSCI and Extrachromosomal Array. All work in making a transgenic line is performed in the USA.


Service Offerings

Mutation via CRISPR Gene Editing

Study your gene’s function by deleting, mutating, or replacing endogenous content via CRISPR/Cas9 gene editing technology.

Available mutations services:
Knockout | Point Mutation | Precise Deletion | Floxed Allele

Tagging via CRISPR Gene Editing

Tag your gene at the endogenous locus via CRISPR/Cas9 gene editing technology with a fluorescent protein for visualization or with an immunotag for biochemical studies.

Available tagging services:
Degron Tag | Fluorescent Tag | Immunotag


Express your favorite gene under a specific promoter, make a Cre recombinase line, or a transcriptional reporter. Choices include Extrachromosomal array or single-copy insertion via MosSCI technology.

Available expression services:
MosSCI | Extrachromosomal array

C. elegans Inject Express

Expression Validation

Quantify the expression of a transgene by validating gene expression in a C. elegans strain via qPCR.

Injection Services

Choose different ways to have your strains generated. We can start with your gene editing idea, and/or provide you the mix or just do the injection for you.

Service Packages

We offer a variety of C. elegans services packages to fit the needs and budget of every lab.

Choices range from the fast, affordable Custom Injection Mix to the comprehensive Full Build service package, allowing you to customize the components you need to accomplish your gene editing goals.

Our Process


Before you start your project

Consultation with our genome engineering design experts to build the exact custom transgenic you need for your research.


During your project

Bi-weekly updates about the progress made on your project from our team of genome engineers. Key milestones will be noted.


After your project

Receive a validation report that describes the details of your genome edit and shows the evidence that the desired edit was made.

Billing Practices

Full Build and Candidate Lines Projects

InVivo Biosystems bills on a 50/50 service payment plan for Full Build and Candidate Lines projects.

The first 50% is required for project start and is non-refundable. The second 50% is paid at end of the project and is only billable if a line is delivered.

Prices stated are exclusive of all taxes, fees, licenses, duties or levies and, unless otherwise stated in the quotation, transportation charges, freight and insurance.

Custom Injection Mix and Inject Express Projects

Payment in full is due for Custom Injection Mix and Inject Express project start and is non-refundable.

InVivo Biosystems quotations are valid for thirty (30) days unless otherwise stated in the quotation.

Prices stated are exclusive of all taxes, fees, licenses, duties or levies and, unless otherwise stated in the quotation, transportation charges, freight and insurance.

Strain Designation

At the request of WormBase, genetic variation generated and recovered by InVivo Biosystems should retain the “knu # “ allele designation provided.

Allele names can be ascertained from either product shipping documents or by emailing InVivo Biosystems . For example: The strain gene-1(knu123[GFP::gene-1]) was generated by InVivo Biosystems .
