What will you be using the tissue samples for? If you wish to study RNA or proteomics, for example, you may prefer frozen tissues to FFPE blocks, slides or curls. However, FFPE specimens are much more prevalent.
Can you use frozen tissues, serum, plasma or buffy coat, or do you need fresh materials? If you are growing cells, fresh cells are best, but otherwise, frozen specimens are more readily available and less challenging logistically. Samples can be delivered with less time pressure during normal working hours, also reducing your courier costs.
Sourcing biospecimens may require balancing speed of access, numbers of specimens available, logistics and cost to ensure you receive all of the high quality samples you require.
