1. Build your own tissue arrays
2. Master your experimental plans
3. Build up your tissue arrays upon sample availability

4. Build replicate tissue array blocks simultaneously
   The carousel of the Manual Tissue Arrayer I allows the parallel construction of replicates blocks up to 3 copies of the main block. The carousel speeds up operation and reduces handling.

5. Build multiple tissue array blocks concurrently

6. Master the tissue array technique
   The construction technique with the Manual Tissue Arrayer I is simple to master and allows rapid start-up after few days of practice.
   The principle is to drill a cylindrical hole in a sample-free parafin block named the recipient block, then to sample a similar core into the sample block, named the donor block, and to transfer this core into the sample-free block, into the hole made earlier.
   the Manual Tissue Arrayer I is mobile along 2 axes equipped with micrometers to accurately position the punchers within 1 μm.
