Drug Discovery, Drug Delivery, and Biochemical Assays
ProFoldin’s products and services are employed by universities, research institutes, biotech
companies, pharmaceutical R&D and research hospitals worldwide in life sciences and drug discovery.

High Throughput Assays for Drug Targets and Enzymes

ProFoldin offers high throughput assays for validated drug targets. The assays are used for tests of inhibition or IC50 measurement of compounds against the specific drug target proteins and enzymes. The assays are in 96-well or 384-well plate format and suitable for high throughput screening (HTS). The validated drug targets include human proteins for anti-cancer and proteins from bacterial, viral and bacterial phage for anti-infection drug discovery.  ProFoldin also provides enzymes, DNA, enzyme substrates and detection dyes separately for drug target protein characterization, assay optimization and HTS needs.
