Spectrophotometric Determination of Phycobiliprotein Content in Cyanobacterium Synechocystis Tomáš Zavřel1, Dominik Chmelík1,2, Maria A. Sinetova3, Jan Červený1 1Department of Adaptive Biotechnologies, Global Change Research Institute, Czech Academy of Sciences, 2Department of Plant Physiology, Faculty of Science, Masaryk University, 3Laboratory of Intracellular Regulation, Institute of Plant Physiology, Russian Academy of Sciences Here, we present a protocol to quantitatively determine phycobiliprotein content in the cyanobacterium Synechocystis using a spectrophotometric method. The extraction procedure was also successfully applied to other cyanobacteria and algae strains; however, due to variations in pigment absorption spectra, it is necessary to test the spectrophotometric equations for each strain individually.
Gap Junctional Intercellular Communication: A Functional Biomarker to Assess Adverse Effects of Toxicants and Toxins, and Health Benefits of Natural Products Brad L. Upham1, Iva Sovadinová2, Pavel Babica2 1Department of Pediatrics & Human Development, Institute for Integrative Toxicology, Michigan State University, 2RECETOX — Research Centre for Toxic Compounds in the Environment, Faculty of Science, Masaryk University This protocol describes a scalpel loading-fluorescent dye transfer technique that measures intercellular communication through gap junction channels. Gap junctional intercellular communication is a major cellular process by which tissue homeostasis is maintained and disruption of this cell signaling has adverse health effects.
