Ping-pong character of nasturtium-seed xyloglucan endotransglycosylase (XET) reaction.
Plant xyloglucan endotransglycosylase (XET, EC 2.4.1.207) degrades its substrate by a transglycosylation mechanism while endo-cleaving xyloglucan (XG) molecules at their beta-1,4-linked polyglucosyl main chain and transferring the newly generated reducing chain ends to hydroxyls at C-4 of non-reducing glucosyl ends of the main chains of other XG molecules or of low-Mr XG-fragments (OS). Kinetic...
متن کاملQuantification Analysis of Dot Blot Assays for Human Immunodeficiency Virus Type 1 and 2 Antibodies
Objective Dot Blot (DB) assay provides highly specific results, but usually not reliable for quantification of antibody production. The need for a more objective DB assay to provide a better definition of the immune status, against HIV antigens, promoted this study to be done to develop a quantitative DB assay. Material and Methods Dot blot (DB) strips for antibodies directed to human immuno...
متن کاملXyloglucan endotransglycosylase, a new wall-loosening enzyme activity from plants.
1. Cell-free extracts of all plants tested contained a novel enzyme activity (xyloglucan endotransglycosylase, XET) able to transfer a high-Mr portion from a donor xyloglucan to a suitable acceptor such as a xyloglucan-derived nonasaccharide (Glc4Xyl3GalFuc; XG9). 2. A simple assay for the enzyme, using [3H]XG9 and based on the ability of the [3H]polysaccharide product to bind to filter paper, ...

متن کاملDesign and optimization of Dot-blot ELISA system using specific antigens for simple and rapid diagnosis of glanders
Introduction Glanders is one of the oldest contagious and dangerous zoonotic diseases manifesting ulcerative granulomatous lesions on the skin and mucous membranes. Early methods possessing desirable sensitivity and specificity is important to diagnose the disease considering the just only one case report and preventing disease by identification and eradication. The present study was aimed to ...
