Application Notes

Pterine-6-carboxylic acid is a fluorescent endogenous metabolite from various sources including human blood, sheep pineal glands, various amphibians, fish and soybeans. Pterine-6-carboxylic acid is a biomarker for tetrahydrobiopterin deficiency and for various tumors. Pterine-6-carboxylic acid is a photodegradation product of folate and augments ROS production and phototoxicity of UVA towards human cell lines (epidermal carcinoma A431, primary melanoma WM115 and keratinocyte HaCaT).
