Image mouse kidney

Cryo-sectioning is a technique for cutting frozen tissue samples which are then collected on glass microscope slides.

Image PNI
Pronuclear Injection

Pronuclear injection is a very common and well established method used to create transgenic mice. This method is usually used for "gain-of-function" experiments.

Custom AAV Production 

The core provides custom cloning and production of AAVs that are not yet commercially available. Our protocol produces high titer yields of serotypes 2.1 and 8.

Paraffin Sectioning

Paraffin sectioning is the sectioning of tissue in which the water has been replaced with wax.

Blast Injection

In order to study the "loss-of-function" of any given gene it is necessary to replace the endogenous gene with a modified construct.

Colony Management

Breeding colony management services covers day-to-day management and recordkeeping for your colony.

RNA In situ Hybridization

The core offers non-radioactive, RNA in situ hybridization (ISH) on frozen tissue sections primarily from rodent experimental models to determine gene expression patterns.

Image Injection slide

CRISPR is a powerful gene editing tool, especially for the rapid introduction of point mutations and indels. We offer both pronuclear and ES cell-based approaches. 

Image PCR genotyping 2
PCR Analysis

HGeM provides PCR-based genotyping of rodent lines for maintaining and determining trait zygosity. Custom assay development is also available.

Image immunohistochemistry

The core provides a full range of services including consultation, collection of animal tissue specimens, preparation of frozen sections, and documentation and quantification of expression patterns by microscopy. 

Image recombineering, floxed gene construction
Custom Cloning - Recombineering

Recombineering (recombination-mediated genetic engineering) is a novel and powerful method which enables fast and efficient construction of vectors to generate complex gene modifications in the mouse genome.

Rederivation, Cryopreservation, IVF

Rederivation and Cryopreservation of mouse germplasm are essential tools for anyone working with mouse mutant strains. In vitro fertilization (IVF) is performed to recover a mouse strain from frozen sperm. 

Image H&E

The standard histological stain is Hematoxilin and Eosin (H& E). This type staining is often use for quick analysis of tissue.

Gene Targeting

In order to modify endogenous genes, it is necessary to perform gene targeting. A vector containing a modified copy of the gene of interest is electroporated into mouse embryonic stem (ES) cells.

Image Acquisition

We offer high resolution, full-slice acquisition of epifluorescent and brightfield images. These images are suitable for anatomical analysis of gene expression patterns and viral infection.
