Polyamine and Paraquat Transport Assays in Arabidopsis Seedling and Callus
[Abstract]  Polyamines (PAs) are polycationic compounds found in all living organisms and play crucial roles in growth and survival. We here show the ‘Polyamine and paraquat (PQ) transport assay’ protocol, which can be used to examine the uptake activity of PA/PQ transporters. We have used this protocol to demonstrate that PUT3 in Arabidopsis is a polyamine transporter and is able to take up spermidine and its analog paraquat.

Fat Turnover Assay in Drosophila
[Abstract]  Like all animals, Drosophila shows robust fat (triglyceride) turnover, i.e., they synthesize, store and utilize triglyceride for their daily metabolic needs. The protocol describes a simple assay to measure this turnover of triglycerides in Drosophila.

A Filter Binding Assay to Quantify the Association of Cyclic di-GMP to Proteins
[Abstract]  Cyclic di-GMP (c-di-GMP) is a ubiquitous second messenger that regulates many processes in bacteria including biofilm formation, motility, and virulence (Hengge, 2009). Analysis of c-di-GMP binding properties of bacterial proteins is an important step to characterize c-di-GMP signaling pathways. C-di-GMP binds numerous proteins such as transcription factors, enzymes, and multimeric protein complexes (Hickman and Harwood, 2008, Ryjenkov et al., 2006, Weinhouse et al., 1997). ...
