Chemical Probes

SGC chemical probes are open-access reagents that are meant to be used by the biomedical research community with no restrictions on use. SGC-developed probes are complemented by a growing set of donated high-quality chemical probes developed in industry and non-SGC laboratories. These are also available for unencumbered use.

The table below contains the entire collection of probes from SGC’s chemical probes program and donated chemical probes. To browse the collection, find associated data, or acquire samples, select the desired chemical probe in the table below and follow the links that appear on that page. You can sort the table by clicking the column headers.

For inquiries or requests related to chemical probes or libraries, please contact us at proberequests@thesgc.org.
