Frequently Asked Questions

How is the FKBP listing put together?
It draws on reported FKBP annotations within Cell Cycle/DNA Damage and lists each compound with its structure, identifiers, and the activity published for it. Always check the underlying assay before comparing potency values across entries.
How do I choose a FKBP modulator for my assay?
Start from the assay format and readout — biochemical, cell-based, or in vivo — then compare the FKBP entries on potency, selectivity over related family members, and solubility in your vehicle. Where several chemotypes are available, a reference compound plus a structurally unrelated backup is the usual way to control for off-target effects.
Which specifications matter most for FKBP compounds?
Purity and identity confirmation come first, then solubility in DMSO or your chosen vehicle, recommended storage temperature, and stability in solution. For FKBP work in particular, freshly prepared stocks avoid most of the reproducibility problems seen with stored plates. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
What if the FKBP compound I need is not listed?
Search by CAS number or SMILES first, since analogs of FKBP compounds are often catalogued under a related target. Custom synthesis and bulk enquiries go to [email protected]. We supply verified businesses, research institutions, universities, and government agencies.
