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.
