R&D Use Only Products supplied for research and development use

Enzyme inhibitors and substrates are useful in activity assays, mechanistic studies, screening workflows, and biochemical method development. Selection commonly depends on enzyme class, mode of inhibition or turnover, assay format, potency or kinetic relevance, specificity, and compatibility with detection chemistry. This page helps researchers compare functional biochemical tools around an assay or mechanism rather than around a single catalog keyword. It works well alongside enzymes, buffers, and chemical biology detection reagents.
