# Identifying phycobiliprotein based on wavelength

I have the absorption spectrum of a specific phycobiliprotein. Its maximum wavelength is 620.6 (nm),this is the only data I have. How can I know what type of phycobiliprotein it is?

• Did you try looking it up? Many vendors sell these things and have spectral data available. For instance: interchim.fr/ft/2/28310A.pdf May 20, 2015 at 16:49

I'm afraid that this is pretty much a link-only answer, but based on Spectroscopic Properties of C-Phycocyanin and of Its $\alpha$ and $\beta$ Subunits, published in J. Biol. Chem., 1973, 248, 5679-5685 (PDF) there's a good chance that the phycobiliprotein is C-Phycocyanin.
