This website is open resource describing a variety of in vivo applications, transfection services and in-vivo transfection reagents.

Here you can find information related to DNA transformation, also called DNA transfection, recombinant DNA, genetic transformation, or gene splicing, which is an exciting new field of science.


Injecting of a cell

What does “In Vivo” mean?

When conducting a controlled biological experiment on living cells, there are generally two main categories almost all experiments fall under:

They are named, quite colloquially, “in-vitro” and “in-vivo”.


As the picture illustrates, in vitro is Latin for “within glass”.

In contrast, in vivo is Latin for “within the living”.

Fundamentally, in vivo includes experiments conducted on living, breathing (in one form or another) multicellular organisms. In vitro includes experiments conducted in some manner of container, usually focusing on specific, singular types of simple organisms and/or tissues.

Both forms of experimentation rely on the study of living cells. It’s important to note that the difference here isn’t life and death, since both the breathing animal and the cells in the petri-dish are both technically alive.

This is an important distinction to make because in different places there can be very different government regulations regarding conducting scientific experiments upon living animals. If you are looking for a DNA transfection services, we highly recommend making sure they are compliant with all of the appropriate legal, as well as ethical, rules, guidelines and regulations.

Altogen Labs, our sponsors, provide products and services related to in vivo siRNA Delivery. These products can be useful when studying small rodents such as rats or mice.
