Presented here is the protocol for using the new LP 110 optical device for taking ground-based in situ LAI measurements. Environment Leaf Area Index Estimation Using Three Distinct Methods in Pure Deciduous Stands Jakub Černý1, Radek Pokorný2, Pavel Haninec2,3, Pavel Bednář1 1Forestry and Game Management Research Institute, Research Station at Opočno, 2Department of Silviculture, Mendel University in Brno, 3Department of Forest Botany, Dendrology and Geobiocenology, Mendel University in Brno An accurate estimation of leaf area index (LAI) is crucial for many models of material and energy fluxes within plant ecosystems and between an ecosystem and the atmospheric boundary layer. Therefore, three methods (litter traps, needle technique, and PCA) for taking precise LAI measurements were in the presented protocol. Chemistry DNA-magnetic Particle Binding Analysis by Dynamic and Electrophoretic Light Scattering Yazan Haddad1,2, Simona Dostalova1,2, Jiri Kudr1,2, Ondrej Zitka1,2, Zbynek Heger1,2, Vojtech Adam1,2 1Department of Chemistry and Biochemistry, Mendel University in Brno, 2Central European Institute of Technology, Brno University of Technology This protocol describes the synthesis of magnetic particles and evaluation of their DNA-binding properties via dynamic and electrophoretic light scattering. This method focuses on monitoring changes in particle size, their polydispersity and zeta potential of particle surface which play major role in binding of materials such as DNA.
