Custom Gene-Edited C. elegans From An Officially Licensed CRISPR 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 over 3,000 C. elegans transgenic lines to researchers who rely on our genome-edited strains to generate data and publish results and seek affordable therapeutics in rare diseases.
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.
Types of Edits
We work with you on project design using a collaborative approach to ensure that you receive the C. elegans line best suited for your experiments.

Transgenic Design
We collaborate with you to understand your gene expression expectations. This allows us to find the most optimal promoter, coding, and terminator sequences to maximize the chance of successful strain generation. We listen to your needs and adapt the project accordingly.
Molecular Assembly
Depending on the project approach, we often turn to de novo sequence generation through our suppliers. Alternatively, we can deploy a variety of gene assembly approaches to get the exact sequence needed for appropriate tissue-specific expression. Either way, we efficiently generate the sequence components needed for creation of high efficiency injection mix components.
C. elegans Injections
With thousands of lines delivered, our team of injectionist have the necessary skill. They can obtain precision delivery of transgenesis reagents to the nematode gonad. Often, only a few animals need to be injected in order to generate multiple biological replicates.
Candidate Screening
We perform a sufficient number of injections that typically 3 or more biological replicates are generated.
Occasionally the numbers of animals transformed is below this number in a set of injected animals. When this is detected, we quickly redo another set of injections to ensure that you received a good chance at multiple biological replicate strains.Strain Confirmation
Often our process has a selection marker that helps us identify candidates, but we don't stop there. For our genomic integrants, we look at each transgenesis junction by PCR. Once we confirm the ends of the gene insertion have proceeded as planned, clients can opinion for full sequencing of the entire transgene sequence so that a sequence verified strain is delivered.

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 .
Frequently Asked Questions
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. As an expert in C. elegans genome editing, we have developed many unique internal processes to ensure the quality of the strains, including plasmid validation, injection protocol, and to improve our editing efficiency. Choices of genome editing methods are CRISPR, MosSCI and Extrachromosomal Array.
C. elegans has become a key model for understanding the molecular mechanisms involved in a growing number of human diseases. Having a short generation time along with invariant developmental lineage, C. elegans has proved to be extremely beneficial for understanding basic cell biology, neurobiology and aging. Another unique advantage of C. elegans over other multicellular model organisms is that individuals can be frozen indefinitely and revived to obtain an F2 generation within a week, thus eliminating the cost of maintaining colonies of mutants
Yes, our strain and allele designation have been confirmed by the WormBase, and any genetic variation generated and recovered by InVivo Biosystems should retain the designated “knu # “ allele name. 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 .
We enable you to tag your favorite gene at the native locus via CRISPR/Cas9 gene editing technology choosing from a large selection of fluorescent proteins, immunotags and degron tags. Custom tags and combinations (i.e. GFP::3xFLAG, etc.) are also available.
InVivo Biosystems has the capability to make specific DNA alterations including knockout, point mutation, precise deletion, and floxed allele with high precision which enables you to study gene function in exciting new ways.
We offer MosSCI and Extrachromosomal array with varying cost and delivery time. Please view our package details for further information.
Our Expression Validation assay, which can be performed on a new or existing strain will allow you to:
- Demonstrate that gene expression has been eliminated in your knockout strain.
- Assay whether your point mutation results in a difference in gene expression.
- Determine the relative level of expression from your transgene.
- Investigate whether the addition of a tag at the native locus has altered gene expression.
Yes, we offer custom injection services where you provide the gene editing idea in your strain receive professionally prepared injection mix containing all of the required molecular components to achieve your desired custom genetic edit. You will, however, require access to microinjection rig, technical skills for proper injection, and the ability to screen and select final desired strain(s).
