Physico-chemical analysis of Nostoc sp. R76DM phycocyanin (N-PC). (A) SDS-PAGE profiles of purified N-PC. M, Molecular weight marker; PC, Purified N-PC; S, Silver-stained; Z, Zinc acetate stained. (B) Steady state UV-visible (Intact line) and fluorescence emission (Dashed line) spectra of purified N-PC. Fluorescence emission spectra were recorded upon exciting the N-PC at 580 nm. (C) Deconvoluated absorption spectrum of N-PC having three (denoted by 1, 2, and 3) Gaussian components. The Gaussian-fitted (sum of deconvoluated components) and experimental absorption spectra are denoted as 4 and 5, respectively.
