Filipin (from Streptomyces filipinensis)
Filipin is highly fluorescent polyene macrolide that binds specifically to cholesterol. It is widely used as a histochemical fluorescent stain for cholesterol. This method of detecting cholesterol in cell membranes is used clinically in the study and diagnosis of Type C Niemann-Pick disease. (This product is for research use only)
Filipin is a polyene antifungal antibiotic produced naturally by the bacteria Streptomyces filipinensis.
