Rpe65 Variants Affect Vision in Animal Models

Vision researchers are very familiar with several mutations which can affect sight in mice. Chang et al. cataloged 16 separate mutations causing retinal degeneration. Two of the better known mutations are Pde6brd1 (commonly called rd1) and Crb1rd8 (commonly called rd8). The rd1 mutation is present in a number of inbred strains, such as FVB and SJL, and causes blindness by weaning age. The rd8 mutation is present...

Should You Breed or Buy Your Own Rodent Models?

Many research investigators are faced with a decision: should they buy laboratory rodents from a commercial vendor, or produce them with an in-house breeding colony? There are many factors to evaluate before the decision to "breed or buy" can be made. Following are a few questions and considerations that must be addressed before an informed decision can be made: Are the rodents available from a commercial vendor?...

"Collaborative Research Organizations" Are Your New CRO

Over the last two decades, the pharmaceutical industry has faced increasing challenges: declining R&D productivity, rising costs, competition from generics, greater regulatory complexity, and changing expectations of patient-centered healthcare. In response to these pressures, many companies are transforming the way in which medicines are discovered, developed, and brought to market. Two key trends are emerging: The proliferation of digital biotechs The externalization of drug development Contract Research...

Cryopreservation in Colony Management

Use of genetically engineered rodent models in research requires the lines to be maintained in continuous breeding, which is costly, labor intensive, and takes up limited vivarium space. Also when such colonies are the sole source of the model, there is risk of losing the line altogether to unanticipated death, disease, infertility, genetic drift, or microbial contamination. Effective use of cryopreservation allows researchers to better utilize financial...

A Successful Breeding Plan in Five Steps

"It's just breeding... right?" You may want to carry out large cohort studies within the next 4-6 months, or to quickly recover a cryopreserved line from your collaborator to cross with your own knockout line. How difficult can it be? The temptation of getting there fast may make you plunge into a new project right away. But early missteps in colony management can surface months into a...

Easier Said than Bred: 4 Considerations for Breeding Laboratory Mice

Have you ever had a mouse infestation in your house? This is a pesky problem that can prove difficult to resolve. After all, they breed like... well, mice. So why is it so difficult to breed laboratory mice? Laboratory mice are purpose-bred for specific phenotypes or traits, not to optimize litter size. Quite often, fecundity is sacrificed to attain traits desired for laboratory mouse studies, or breeding...

Why Would You Want a Black 6 Mouse That Isn't Black?

Taconic Biosciences introduced two new B6 albino models in late 2012 and early 2013. The B6 Albino A++ (model 11227) and the B6 Albino (model 11971) were generated at Taconic’s Cologne, Germany, site via gene targeting technology. These models represent the first albino B6 models available on the C57BL/6NTac (Taconic B6) background. We all know that the B6 strain is black…so why would you want an albino...
