    Analysis of Metals in Whole Cells, Thylakoids and Photosynthetic Protein Complexes in Synechocystis sp. PCC6803
    Authors:  Chiara Gandini, Søren Husted and Sidsel Birkelund Schmidt, date: 06/20/2018, view: 3769, Q&A: 0
    [Abstract] Metals are essential in many biological processes, including oxygenic photosynthesis. Here we described a method to measure the metal pool in whole cells and thylakoids, including the bioactive pool in intact photosynthetic protein complexes in the model oxygenic cyanobacterium Synechocystis PCC6803. In the first part of the protocol, ...
    Determination of Mn Concentrations in Synechocystis sp. PCC6803 Using ICP-MS
    Authors:  Fabian Brandenburg, Hanan Schoffman, Nir Keren and Marion Eisenhut, date: 12/05/2017, view: 5984, Q&A: 0
    [Abstract] Manganese (Mn) is an essential micronutrient for all photoautotrophic organisms. Two distinct pools of Mn have been identified in the cyanobacterium Synechocystis sp. PCC 6803 (Synechocystis), with 80% of the Mn residing in the periplasm and 20% in cytoplasm and thylakoid lumen (Keren et al., 2002). In this protocol, we ...
    Heavy Metal Stress Assay of Caenorhabditis elegans
    Authors:  Strahil Iv. Pastuhov, Tatsuhiro Shimizu and Naoki Hisamoto, date: 06/05/2017, view: 8442, Q&A: 0
    [Abstract] Organisms have developed many protective systems to reduce the toxicity from heavy metals. The nematode Caenorhabditis elegans has been widely used to determine the protective mechanisms against heavy metals. Responses against heavy metals can be monitored by expression of reporter genes, while sensitivity can be determined by quantifying ...
    Determination of Elemental Concentrations in Lichens Using ICP-AES/MS
    [Abstract] Lichens are good biomonitors for air pollution because of their high enrichment capability of atmospheric chemical elements. To monitor atmospheric element deposition using lichens, it is important to obtain information on the multi-element concentrations in lichen thalli. Because of serious air pollution, elemental concentrations in thalli of ...
