Speed Line Expansion/ Congenics

These services are currently only available for mice.  We use generation of fertilized embryos by natural mating or IVF, and embryo transfer into pseudopregnant recipients in order to quickly expand a line or move an existing mutation or variant onto a new genomic background.

For speed congenics, we use IVF to speed up the time between successive generations required to transfer a mutation or variant onto a new genomic background, by collecting embryos from 3 week old females from a line of interest and performing IVF with sperm from a pure background male.

Speed line expansion is performed using the same procedure as speed congenics and is useful if a large cohort of animals is to be generated with the assistance of IVF.

All rates listed are per session, for multiple generations, multiple sessions will be required.
