Projection of the z-series stack.ACKNOWLEDGMENTSWe thank Sebastian Bednarek (University of Wisconsin, Madison), F ix Kessler (University of Neuchatel), Norbert Rolland (Commissariat l’Energie Atomique), Natasha Raikhel (University of California, Riverside), Erik Nielsen (University of Michigan), Laurent Blanchoin (Commissariat l’Energie Atomique), and Liwen Jiang (Chinese University of Hong Kong) for offering antisera, also as Andreas Nebenf r (University of Tennessee, Knoxville) for the Arabidopsis line expressing mannosidase-YFP utilized within this study. The JLA-20 monoclonal anti-actin was obtained from the Developmental Research Hybridoma Bank created under the auspices of your Eunice Kennedy Shriver National Institute of Youngster Well being and Human Development and maintained by the University of Iowa.

J Cell Biol 134: 38999Immunofluorescence Image AnalysisMetaMorph computer software (version six) was made use of for image evaluation and to quantify the extent of AtCP and actin colocalization. ROIs were selected from every single image so that you can maximize the area of cells analyzed. Individual images had been thresholded, depending on the antibody control images, and standard threshold values have been 30 to 80. The extent of colocalization was determined involving the two channels as previously described (Zhang et al., 2010). The Pearson correlation coefficient (PCC) is actually a quantitative measurement that estimates the degree of overlap amongst fluorescence signals obtained in two channels (Barlow et al., 2010; Zinchuk et al., 2013). PCC values variety from 1.0 (which indicates comprehensive colocalization of two structures) to 0 (which indicates no substantial correlation) to 21 (which indicates total separation of two signals).
