4 key animal research insights from AALAS 2018

By Jennifer Brooks

The 69th American Association for Laboratory Animal Science (AALAS) National Meeting recently took place in Baltimore, Maryland.  A forum for those dedicated to the humane care and treatment of laboratory animals, delegates from the academic community, research institutions, government organizations and commercial companies came together to enjoy a series of scientific lectures, poster sessions and exhibits. Delegates also received the latest industry news and insights, including updates from regulatory agencies which we’ve summarized into key take home messages.

Diet selection 101 - Making informed decisions about lab animal diets

By Luz Merle

Diet continues to be an overlooked variable in experimental investigations, impacting reproduction, growth, and disease, as well as affecting the response to experimental manipulation in laboratory animals.

Given that reproducibility is a key principle in the conduct and validation of experimental science, how can you ensure that your laboratory animal diet does not unduly influence your outcomes and conclusions drawn from your empirical data?

To answer this question, let’s discuss the function of a diet as a research tool and examine some of the key considerations in choosing the most optimal diet for your study’s needs.

5 smart strategies to improve animal welfare

By Brad Gien

The research industry is increasingly relying on new techniques and technologies to improve animal welfare. Improvements have been limited as paper-based systems can cause issues with access and accuracy, while electronic documents face challenges with tracking and compliance. We've been focused on reducing animal usage and furthering the 3Rs – replacement, refinement and reduction, through the use of innovative technology that monitors the proficiency of surgeons and tracks surgery of models, and we'd like to share our findings with you. Learn about this system and its strategies to improve surgical performance – and animal welfare.

5 reasons why the R2G2® mouse could help you achieve your oncology research milestones

By Jamie Naden

The R2G2® mouse has the potential to help you break new ground in investigational cancer therapies. In two recent studies, this model tolerated standard of care chemotherapy and estrogen supplementation well in terms of overall survival and changes in body weight. Here are five reasons why this mouse model could serve as an excellent host for your preclinical human tumor xenograft studies.

3 reasons why Wistar Han® could be the perfect model for your study

By Mandy Horn

The selection of your animal model for toxicity and carcinogenicity testing plays an essential role in the accuracy of your study findings. Our researchers recently completed a two-year study of 130 male and 130 female Envigo RccHan®:WIST (Wistar Han®) rats and compared them to other outbred rats (e.g., Sprague-Dawley®, Fischer 344). Here, we share the results of the study.

The results provided insights on how Wistar Han provided numerous advantages, such as smaller body size, higher rates of survival and lower tumor/lesion incidence, as compared to CRL:CD®(SD) (CD) rat models that were the subjects of a previous two-year study.

How can cryopreservation safeguard vulnerable model strains?

By Luz Merle

You’ve spent years building the ideal colony for your study – and have invested even more resources into maintaining it for future usage. Imagine that after investing time and money developing and maintaining your colony, it could become redundant due to a natural disaster, microbial contamination, or facility failure. And, given the increased use of immunodeficient models and sensitive microbiota research projects, along with the cost and complexity of model breeding, cryopreservation should be woven into the fabric of each and every research project.

4 key considerations when selecting a rodent surgical model

By Brad Gien

Animal catheterization serves a valuable tool to reduce experimental variability in several ways. It allows for consistent dosing as well as consistent blood sampling, while at the same time decreasing stress to animals and their handlers. But not all catheter types are created equally. Understanding the different options will help you select the optimal rodent surgical model for your study.
