Drug aliquots, DSRT- and custom drug plates are available on request

FIMM/HTB distributes aliquots of available chemical compounds to academic research groups in Finland for a small fee covering the actual compound costs and handling.

A list of available chemical compounds can be found :
How to order drug aliquots and drug plates:

All compound aliquot, custom drugged plate and DSRT set reservations/orders should be done two weeks in advance via . 

For further information contact us at

Please be prepared to provide the following information:

  1. Invoicing information with the order: PI and WBS number.
  2. All preordered sets and aliquots will be charged according to the order placed in iLAB, not by use.
  3. For specific compound aliquots the name of the compound is not sufficient alone. Write also FIMM-ID and/or Supplier Reference to the order.
  4. New DSRT sets are made every other week. Sets are kept in stock for patient samples.
  5. Custom druggings are also made every other week, the weeks when DSRT sets are not made.
  6. Compound aliquots are prepared every other Tuesday and can be picked up on Wednesday. Aliquots are stored in the storage pods, and can be picked up whenever needed.

We hand out only unopened tubes/boxes of reagents (CTG, CTB, CellTox etc.) and empty assay plates (20 plates/box). We will still continue ordering big bulks for the better prices.
