Evidence for the presence of a second electron donor for the cytoplasmic thioredoxins in the yeast Saccharomyces cerevisiae
(TÜBİTAK, 2006)In yeast, the cytoplasmic thioredoxin system is composed of NADPH, thioredoxin reductase-1 (TRR1) and 2 thioredoxin genes (TRX1, TRX2). In this study, using yeast knockout mutants for TRR1, TRX1 and TRX2 genes, the role ... -
Partial purification of hen egg white lysozyme by ethanol precipitation method and determination of the thermal stability of its lyophilized form
(TÜBİTAK, 2007)Lysozyme was partially purified from hen egg white by precipitation of non-lysozyme protein impurities during incubation in the prence of ethanol. The thermal stability of the obtained partially purified enzyme was also ... -
Optimization of transfection of green fluorescent protein in pursuing mesenchymal stem cells in vivo
(Turkish Society of Hematology, 2008)Objective: Green Fluorescent Protein (GFP) has been used as a marker of gene expression and a single cell marker in living organisms in cell biology studies. The important areas that GFP is used are expression levels of ... -
