Extraction of Intracellular and Cell Wall Proteins from Leaves and Roots of Harsh Hakea
[Abstract]  Plant proteins can be targeted to intracellular (i.e., cytosol, vacuole, organelles etc.) or extracellular (i.e., cell walls, apoplast) compartments. Dual targeting is a key mechanism with important implications for plant metabolism, growth, development and defense etc. Harsh Hakea (Hakea prostrata R.Br.) is a perennial species and member of the Proteaceae family that thrives on extremely phosphate impoverished soils of southwestern Australia. Harsh ...

Protein Sample Preparation for Proteomic Analysis in Leishmania donovani
[Abstract]  Leishmania is a genus of trypanosomatid protozoa and is the parasite responsible for the disease leishmaniasis. These protozoa, regulate their gene expression in an atypical way, compared to other higher eukaryotes. The regulation of gene expression is characterized by a predominance of post-transcriptional over pre-transcriptional regulatory mechanisms (Clayton, 2002). Thus proteomic analysis has proven an essential tool for understanding pathways implicated in Leishmania ...

Protein Extraction, Acid Phosphatase Activity Assays, and Determination of Soluble Protein Concentration
[Abstract]  Acid phosphatases (APases) catalyze the hydrolysis of inorganic phosphate (Pi) from a broad range of Pi-monoesters with an acidic pH optimum. The liberated Pi is reassimilated into cellular metabolism via mitochondrial or chloroplastic ATP synthases of respiration or photosynthesis, respectively. Eukaryotic APases exist as a wide variety of tissue- and/or cellular compartment-specific isozymes that display marked differences in their physical and kinetic properties. Increases in intracellular ...
