Genome Editing Shared Resource

Overview of Services

The Genome Editing Shared Resource of Rutgers-CINJ (GESR) is a state-of-the-art university core facility that offers services related to the creation of mouse and cell line models for the Rutgers research community. GESR utilizes the latest in genome editing technologies, particularly CRISPR-Cas9, to make precise genetically modified animals and custom modified cell lines tailored to the needs of our investigators.

In addition to gene editing, GESR offers traditional services such as DNA/BAC microinjection to make transgenic mouse lines. The GESR can assist investigators in banking their lines by sperm or embryo cryopreservation.                                                                                                          

GESR utilizes in vitro fertilization (IVF) and embryo rederivation to facilitate import of lines from external sources or from rooms of lower health status into clean facilities. IVF may also be used to quickly expand colonies.  

Rutgers GESR offers the following services:

  • Mouse model generation
  • Cell line gene editing
  • Mouse line cryopreservation
  • Mouse line rederivation
  • Design and production of CRISPR vectors
  • PCR Genotyping
  • Founder breeding



The GESR can also work with you on special projects to study embryonic development, in vivo gene editing/therapeutic models and control of gene expression using CRISPR-based activators/repressors that go beyond gene editing.


WHAT'S NEW and AVAILABLE from Rutgers Genome Editing Shared Resource in 2024?

 EFFECTIVE 11/01/23 - GESR fee increase. Projects initiated after 11/01/23 will be charged new fees. Additional services added to exsisting projects after 11/01/23 will also be charged new fees. 


FYI - 03/31/22 - GESR will begin billing as projects progress for services rendered as they are completed then finalize billing at completion.


NEW - Cell line gene editing is now offered as a service. We have our own microfluidic fluorescent cell sorter that allows us to generate single-cell clones.

Contact us to discuss your project. 


NEW - Efficient targeting at H11 locus (a safe harbor locus that is an alternative to Rosa26). Expand your repertoire of targeted lines with new reporters expressed from the H11 locus.

Also, instead of making traditional transgenics with variable expression, knock it into H11 instead to get reliable expression and screen fewer lines.

NEW - Direct knock-in into NSG background (or any strain background, just inquire)


NEW - Ask us how you can KO up to 10 genes simultaneously in vivo in a tissue-specific manner using our own experimental conditional Cre-mediated Cas9 expression system.
