Non-radioactive in vitro PINK1 Kinase Assays Using Ubiquitin or Parkin as Substrate
[Abstract]  This protocol describes the in vitro phosphorylation of ubiquitin and Parkin by the kinase PINK1 using recombinant proteins. Both substrates, ubiquitin and Parkin, are phosphorylated at the conserved serine 65 residue (pS65-ubiquitin and pS65-Parkin). The protocol also includes the use of monomeric and K48- and K63-linked poly-ubiquitin chains as alternative substrates. Although there are commercially available antibodies, we have not tested their performance in this assay since, but ...

Cytohistochemical Determination of Calcium Deposition in Plant Cells
[Abstract]  Calcium plays important roles in maintaining plant cellular structure and also acts as a key secondary messenger in intercellular signaling. Thirty years ago, methods of detecting calcium in sub-cellular level had been established (Stockwell and Hanchey, 1982; Borgers et al., 1982) and reviewed extensively (Wick and Heplerm, 1982). We had used the method of testing calcium localization in salt tolerance improved transgenic alfalfa plant (Zhang and Wang, 2015). Here, we describe the ...

Imaging and Measurement of Nanomechanical Properties within Primary Xylem Cell Walls of Broadleaves
[Abstract]  A technique of atomic force microscopy (AFM) called PeakForce quantitative nanomechanical mapping (PeakForce QNM) is an efficient tool for the quantitative mechanobiological imaging of fibrillar aggregate, human epidermal cell and woody plant cell wall topography (Sweers et al., 2011; Heu et al., 2012; Ďurkovič et al., 2012; Ďurkovič et al., 2013). Here, we describe a detailed protocol for the measurement of nanomechanical properties of primary xylem cell ...
