Rapid Colony Development (IVF & Speed Congenics)

Charles River offers programs to speed up the process of establishing an animal research colony and the delivery of study cohorts. These services can help save you significant time, money and resources compared with a natural colony expansion program.

Utilizing in vitro fertilization (IVF), our rapid colony expansion program can take a small colony of animals (as few as two males) and generate hundreds or thousands of animals to establish a breeding colony or perform studies on in as little as 12 weeks. This routine process helps hundreds of clients annually accelerate their research and execute studies faster and more efficiently.

As an additional benefit, our rapid colony expansion program also rederives your colony, ensuring that the animals you receive for research are of VAF/Elite® health status.

Our speed congenics program, Marker-Assisted Accelerated Backcrossing (MAX-BAX®), can deliver a fully congenic colony in only 15 months, saving up to a year and a half in colony development time. This service utilizes a custom-designed 384 SNP marker panel that looks at single nucleotides at 7 Mbp intervals.
