Frequently Asked Questions
How is the CD28 listing put together?
It draws on reported CD28 annotations within Immunology/Inflammation 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 CD28 modulator for my assay?
Start from the assay format and readout — biochemical, cell-based, or in vivo — then compare the CD28 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 CD28 compounds?
Purity and identity confirmation come first, then solubility in DMSO or your chosen vehicle, recommended storage temperature, and stability in solution. For CD28 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 CD28 compound I need is not listed?
Search by CAS number or SMILES first, since analogs of CD28 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.
