Research Considerations
Cell-culture studies with Rigin typically use keratinocytes or fibroblasts exposed to inflammatory stimuli such as UV light, measuring IL-6 release as the primary endpoint.
Quality Control, COA and Shipping
Before any batch reaches the catalog it is tested for purity by HPLC and verified by mass spectrometry against its theoretical mass. A Certificate of Analysis accompanies each shipment, and all material is stored cold and protected from light until dispatch.
