Laboratory Animal Ethics: The Three Rs

Animal models have helped make enormous discoveries and breakthroughs in the last few decades. From Pasteur’s use of sheep to test the ‘Germ Theory’, Pavlov’s classic conditioning experiments in dogs, to Dolly the first cloned mammal, animal research has come a long way. Today, most drugs, vaccines and other pharmaceutical products for medical use are […]

Six Steps to Successful Mouse Genotyping

An essential step in mouse breeding is genotyping them to determine the genotype of every mouse in the litter. It is also useful to differentiate between various groups of experimental mice if any confusion arises. When genotyping, you will be hunting for the specific gene that you want your mice to have or a genetic […]

For the Love of Mouse! How to Start Working with Mice

Researchers have always been in search of model organisms that can be used to study and explore biological phenomena to make discoveries that can be extrapolated to more complex higher organisms like humans. Of the various model organisms developed and used, starting from the ubiquitous E. coli and S. cerevisiae to the humble D. melanogaster […]

Retroviruses – Friends or Foes?

The word ‘retrovirus’ evokes images of HIV, the AIDS pandemic and a desperate worldwide effort to defeat this mighty adversary. But on the flip side, scientific research has managed to tame the virus and use it as a tool for advancement. Retroviruses are commonly used to introduce genes into mammalian cells to express or knockdown […]

Troubleshooting and Optimizing your Mouse Breedings

Anyone working with laboratory animals has probably realized that simply putting two animals together does not always yield new offspring and reliable continuity of the animal line – unfortunately animal husbandry isn’t that simple! Of course, apart from making sure that the two animals put together are from different genders, there are a lot of […]

Culturing Dendritic Cells – the Factors that Matter

Murine bone marrow derived dendritic cells (BMDCs) are one of the easiest primary cell cultures to generate. The beauty lies in the fact that in the end you have a large quantity of robust DCs that can be matured and used to study a variety of DC functions and DC-T-cell interactions. But there are a […]
