Injection Services

We offer 2 types of injection services:

  • Inject Express: you provide the injection mix and we complete the injections and return the worms to you for screening in less than a week.
  • Custom Injection mix: you provide the gene editing idea and we provide you with expertly designed reagents to begin your transgenic project.

5 Simple Steps to Improve Your Injection Success.

Custom Injection Service Process

  1. Strain Growth & Materials Receiving:
    Your injection materials are catalogued upon receiving in our lab, and your strain is maintained under proper conditions by our expert staff in preparation for injection.
  2. Microinjection Of Adult Gonads:
    Our experienced injectionists perform microinjections to your specifications.
  3. Survival Verification:
    We confirm the survival of the injected animals 24 hours after injection and then prepare for shipping.

Service Details

Inject Express Service Details

Inject Express is a fast and affordable way to turn your prepared plasmids into C. elegans strains. You provide the injection mix and we complete the injections and return the worms to you for screening in less than a week.

  • Send us your plasmid and we will  prepare it using our proprietary clean-up method proven to increase transgenic yield.
  • We will then complete your injection mix with your choice of co-markers.
  • Injections are completed in sets of 10 worms.
  • Injected worms are checked at 24 hours post injection for survival, and all surviving animals are sent to the client.
  • We recommend 1 set of worms injected for extrachromosomal array projects and 3 sets of worms injected for MosSCI and CRISPR projects.
  • The Injection Mix Preparation fee applies to each injection mix.

Custom Injection Mix Service Details

 

  • Send us your gene editing idea.
  • Our expert staff will work collaborate with you to design an injection mix that meets your needs.
  • We prepare reagents containing all of the required molecular components to achieve your desired custom genetic edit.

Other Injection Services

Candidate lines service

  • You provide the gene editing idea, we design the reagents, complete the injections and provide animals who have passed our first round of screening.

    Need an alternative C. elegans strain injected?

    • We can do it! We need an additional week to grow a population suitable for injection.
    • A Strain Preparation fee will be applied once per strain.
    • The option to inject into N2, unc-119 (ed3) null, unc-18 null, or various MosSCI strains (ttTi5605, cxTi10882, ttTi14024) is included at no additional charge.

miniMOS

  • Due to temperature requirements, we recommend that we keep your miniMOS projects at our facility post injection (as opposed to shipping the following day) to ensure a higher chance of success.
  • Heat shock screening and shipping of surviving lines can be completed for an additional fee.

In the event of low transgenic yield, we are happy to provide troubleshooting for your injection mix.
