A: As many as you like. The price is based on dispensed volumes, and if you pay for 200 nl you may divide it into multiple plate copies.
For example:
A: For PRC projects, where CBCS is responsible for executing the screen, the follow‑up is free of charge.
Service projects, however, are charged for follow‑up requests (see price list), which is why the initial price is lower.
In the end, the total cost becomes similar.
This adjustment makes invoicing easier for the Compound Center and increases flexibility for both you and CBCS assay enablers.
A: Our definition of follow up includes the hit confirmation, dose response, and analog testing performed after a full library screen:
Hit Confirmation (3‑point)
~1% hit rate is common, though this can vary.
Dose Response (11‑point)
Approximately 30–40 compounds.
Analogs (11‑point)
Maximum of 64 compounds.
Once these steps are complete, follow‑up is considered done, and you are welcome to submit cherrypicking requests.
