Field of Interest: Natural Products From Algae, Light Harvesting Proteins, Photochromes and Photosynthesis sensing

Background: Phycocyanobilin  is a linear pyrrole blue phycobilin based natural product found in Spirulina species that acts a photosensor in light harvesting arrays in photosynthesis ^1,2   It also is a potent peroxyl radical scavenger and is indicative of specific algae species as fluorometric markers of  different photosynthetic antenna pigments .^3,4

** Please Note: This material is sold with a specification of 65% purity.  This compound is known to be susceptible to isomerization under specific conditions.  Unfortunately, during the purity determination for this product, the material is put under the conditions where isomerization may occur. As a result, we have low confidence in the actual purity of this material and the specification is based on our current best methods for analysis.**
