4.1 Sample Types

Samples of various tissue types will have different properties that will require different ways of handling.

1. Blood is not only a liquid, but it also contains many dangerous pathogens. Caution must taken when dealing with blood, including waring the appropriate Personal Protective Equipment (PPE).
2. Brain tissue can be very fatty so homogenization can be more difficult, which affects downstream yields and applications.
3. Fresh tissue can also behave very differently from older tissues. A sample that has been collected and processed immediately will yield different results from one that has sat in the freezer for 3 years (or even just 3 months). This issue is exacerbated if the proper techniques weren’t used to store the tissue.
