Biliverdin Hydrochloride by Molecular Depot is a biliverdin hydrochloride, the green linear tetrapyrrole formed when the haem ring is opened by haem oxygenase. Biliverdin is the direct product of haem breakdown and is reduced to bilirubin by biliverdin reductase, and the same tetrapyrrole serves as the light-absorbing chromophore of the bacterial phytochromes. It is used as a chromophore in bacterial phytochrome and near-infrared fluorescent protein work, as a reference standard in bile pigment analysis and in haem oxygenase research. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
